Affliction Issues

What is the current situation with measles, mumps, and rubella in the United States?

In 2019, a provisional total of i,242 cases of measles from 31 states were reported to CDC. This was the largest number reported in a single year since 1992; 73% of cases were associated with outbreaks among unvaccinated people in New York. These outbreaks were contained and stopped before the end of 2019. Between Jan 1 and Baronial xix, 2020, merely 12 measles cases were reported by vii jurisdictions. Limited travel as a result of the COVID-19 pandemic drastically reduced opportunities for travelers infected with measles to enter or travel inside the The states. CDC measles surveillance updates tin exist constitute at world wide web.cdc.gov/measles/cases-outbreaks.html.

Since the pre-vaccine era, at that place has been a more than 99% decrease in mumps cases in the United States. Yet, outbreaks still occasionally occur. In 2006, there was an outbreak affecting more than half dozen,584 people in the United States, with many cases occurring on college campuses. In 2009, an outbreak started in close-knit religious communities and schools in the Northeast, resulting in more than than three,000 cases. Since 2015, numerous outbreaks have been reported across the US, in college campuses, prisons, and close-knit communities, including a big outbreak in northwest Arkansas where almost 3,000 cases were reported in 2016. These outbreaks take shown that when people with mumps have close contact with a lot of other people (such as amongst residential higher students and families in close-knit communities) mumps tin can spread even among vaccinated people. However, outbreaks are much larger in areas where vaccine coverage rates are lower. A provisional full of 3,484 cases of mumps were reported to CDC in 2019.

Rubella was alleged eliminated (the absenteeism of endemic transmission for 12 months or more) from the United States in 2004. Fewer than 10 cases (primarily import-related) have been reported annually in the The states since elimination was declared. Rubella incidence in the United states has decreased by more than 99% from the pre-vaccine era. A provisional total of iii cases of rubella, and no cases of built rubella syndrome, were reported in 2019.

How serious are measles, mumps, and rubella?

Measles tin can lead to serious complications and decease, even with modern medical care. The 1989–1991 measles outbreak in the U.S. resulted in more than 55,000 cases and more than than 100 deaths. In the United states of america, from 1987 to 2000, the most commonly reported complications associated with measles infection were pneumonia (6%), otitis media (7%), and diarrhea (8%). For every 1,000 reported measles cases in the United States, approximately 1 example of encephalitis and two to three deaths resulted. The risk for decease from measles or its complications is greater for infants, young children, and adults than for older children and adolescents.

Mumps well-nigh commonly causes fever and parotitis. Upwardly to 25% of persons with mumps have few or no symptoms. Complications of mumps include orchitis (inflammation of the testicle) and oophoritis (inflammation of the ovary). Other complications of mumps include pancreatitis, deafness, aseptic meningitis, and encephalitis. Mumps illness is typically milder, with fewer complications, in fully vaccinated case patients.

Rubella is generally a mild illness with low-grade fever, lymphadenopathy, and angst. Upward to 50% of rubella virus infections are subclinical. Complications tin can include thrombocytopenic purpura and encephalitis. Rubella virus is teratogenic and infection in a pregnant woman, especially during the offset trimester can outcome in miscarriage, stillbirth, and nascence defects including cataracts, hearing loss, mental retardation, and congenital centre defects.

What are the signs and symptoms healthcare providers should look for in diagnosing measles?

Healthcare providers should suspect measles in patients with a febrile rash illness and the clinically uniform symptoms of coughing, coryza (runny nose), and/or conjunctivitis (scarlet, watery eyes). The disease begins with a prodrome of fever and malaise earlier rash onset. A clinical case of measles is defined every bit an illness characterized by

• a generalized rash lasting 3 or more days, and • a temperature of 101°F or higher (38.3°C or higher), and • cough, coryza, and/or conjunctivitis.

Koplik spots, a rash present on mucous membranes, are considered pathognomonic for measles. Koplik spots occur from ane to 2 days before the measles rash appears to 1 to two days afterwards. They appear as punctate blue-white spots on the vivid blood-red background of the buccal mucosa. Pictures of measles rash and Koplik spots can be establish at www.cdc.gov/measles/almost/photos.html.

Providers should be particularly enlightened of the possibility of measles in people with fever and rash who have recently traveled away or who take had contact with international travelers.

Providers should immediately isolate and report suspected measles cases to their local wellness section and obtain specimens for measles testing, including viral specimens for confirmation and genotyping. Providers should also collect blood for serologic testing during the kickoff clinical run across with a person who has suspected or probable measles.

What should our clinic do if we suspect a patient has measles?

Measles is highly contagious. A person with measles is infectious upward to 4 days before through iv days after the day of rash onset. Patients with suspected measles should be isolated for 4 days after they develop a rash. Airborne precautions should exist followed in healthcare settings past all healthcare personnel. The preferred placement for patients who require airborne precautions is in a single-patient airborne infection isolation room. Providers should immediately isolate and report suspected measles cases to their local health department and obtain specimens for measles testing, including serum sample for measles serologic testing and a throat swab (or nasopharyngeal swab) for viral confirmation.

Measles is a nationally notifiable disease in the U.S.; healthcare providers should written report all cases of suspected measles to public wellness authorities immediately to assistance reduce the number of secondary cases. Do not wait for the results of laboratory testing to report clinically-suspected measles to the local health section.

More than information on measles disease, diagnostic testing, and infection control tin be found at www.cdc.gov/measles/hcp/alphabetize.html.

How long does it take to prove signs of measles, mumps, and rubella after being exposed?

For measles, at that place is an average of ten to 12 days from exposure to the appearance of the offset symptom, which is usually fever. The measles rash doesn't normally appear until approximately 14 days after exposure (range: seven to 21 days), and the rash typically begins 2 to four days after the fever begins. The incubation menses of mumps averages sixteen to 18 days (range: 12 to 25 days) from exposure to onset of parotitis. The incubation menses of rubella is fourteen days (range: 12 to 23 days). All the same, every bit noted in a higher place, up to half of rubella virus infections cause no symptoms.

Vaccine Recommendations Back to top

What are the current recommendations for the use of MMR vaccine?

The nearly recent comprehensive ACIP recommendations for the use of MMR vaccine were published in 2013 and are available at www.cdc.gov/mmwr/pdf/rr/rr6204.pdf. MMR vaccine is recommended routinely for all children at historic period 12 through 15 months, with a second dose at age 4 through six years. The 2nd dose of MMR can be given as early on as 4 weeks (28 days) after the first dose and be counted as a valid dose if both doses were given after the kid's get-go birthday. The 2d dose is not a booster, but rather is intended to produce amnesty in the pocket-sized number of people who fail to respond to the outset dose.

Adults with no evidence of immunity (evidence of amnesty is defined every bit documented receipt of one dose [2 doses four weeks autonomously if high take chances] of alive measles virus-containing vaccine, laboratory bear witness of immunity or laboratory confirmation of disease, or birth earlier 1957) should get 1 dose of MMR vaccine unless the adult is in a high-risk group. High-risk people need 2 doses and include school-historic period children, healthcare personnel, international travelers, and students attention post-loftier school educational institutions.

Live attenuated measles vaccine became bachelor in the U.S. in 1963. An ineffective, inactivated measles vaccine was also available in the U.South. in 1963–1967. Combined MMR vaccine (MMRII, Merck) was licensed in 1971. For people who previously received a dose of measles vaccine in 1963–1967 and are unsure which type of vaccine it was, or are sure it was inactivated measles vaccine, that dose should be considered invalid and the patient revaccinated as age- and risk-appropriate with MMR vaccine. At the discretion of the state public health section, anyone exposed to measles in an outbreak setting can receive an additional dose of MMR vaccine fifty-fifty if they are considered completely vaccinated for their age or risk status.

What is considered acceptable evidence of immunity to measles?

Acceptable presumptive evidence of immunity against measles includes at to the lowest degree 1 of the post-obit:

• written documentation of adequate vaccination: • laboratory evidence of amnesty • laboratory confirmation of measles (exact history of measles does not count) • birth before 1957

Although nascence earlier 1957 is considered acceptable evidence of measles immunity, healthcare facilities should consider vaccinating unvaccinated personnel born before 1957 who practise not accept other bear witness of immunity with 2 doses of MMR vaccine (minimum interval 28 days).

During an outbreak of measles, healthcare facilities should recommend ii doses of MMR vaccine at the appropriate interval for unvaccinated healthcare personnel regardless of birth twelvemonth if they lack laboratory evidence of measles immunity.

For which adults are 0, 1, or ii doses of MMR vaccine recommended to prevent measles?

Zero, one, or 2 doses of MMR vaccine are needed for the adults described below.

Zero doses:

• adults built-in before 1957 except healthcare personnel* • adults born 1957 or later who are at low risk (i.due east., not an international traveler or healthcare worker, or person attending higher or other mail service-loftier school educational establishment) and who have already received 1 or more documented doses of alive measles vaccine • adults with laboratory evidence of immunity or laboratory confirmation of measles

1 dose of MMR vaccine:

• adults born 1957 or later who are at low risk (i.e., not an international traveler, healthcare worker, or person attending higher or other post-high school educational establishment) and take no documented vaccination with live measles vaccine and no laboratory evidence of immunity or prior measles infection

Two doses of MMR vaccine:

� high-gamble adults without whatever prior documented live measles vaccination and no laboratory evidence of immunity or prior measles infection, including:

Persons who previously received a dose of measles vaccine in 1963–1967 and are unsure which type of vaccine it was, or are sure it was inactivated measles vaccine, should be revaccinated with either 1 (if depression-risk) or two (if high-run a risk) doses of MMR vaccine.

* Healthcare personnel born before 1957 should exist considered for MMR vaccination in the absence of an outbreak, simply are recommended for MMR vaccination during outbreaks.

Given the risk of outbreaks of measles in the U.S., should all healthcare personnel, including those born earlier 1957, take 2 doses of MMR vaccine?

Although birth before 1957 is considered acceptable bear witness of measles amnesty for routine vaccination, healthcare facilities should consider vaccinating unvaccinated healthcare personnel (HCP) born earlier 1957 who do not accept laboratory evidence of measles immunity, laboratory confirmation of disease, or vaccination with two accordingly spaced doses of MMR vaccine.

However, during a local outbreak of measles, all healthcare personnel, including those born before 1957, are recommended to have 2 doses of MMR vaccine at the appropriate interval if they lack laboratory evidence of measles.

Healthcare facilities should bank check with their state or local health section's immunization plan for guidance. Access contact information here: www.immunize.org/coordinators.

If there is an outbreak in my area, can nosotros vaccinate children younger than 12 months?

MMR tin be given to children every bit immature as six months of age who are at high risk of exposure such as during international travel or a community outbreak. However, doses given BEFORE 12 months of age cannot be counted toward the ii-dose series for MMR.

How does being born before 1957 confer immunity to measles?

People built-in before 1957 lived through several years of epidemic measles earlier the first measles vaccine was licensed in 1963. As a result, these people are very likely to have had measles affliction. Surveys suggest that 95% to 98% of those born before 1957 are immune to measles. Persons built-in earlier 1957 can be presumed to exist immune. Even so, if serologic testing indicates that the person is not allowed, at least 1 dose of MMR should be administered.

Why is a second dose of MMR necessary?

Approximately vii% of people practice not develop measles immunity subsequently the kickoff dose of vaccine. This occurs for a variety of reasons. The second dose is to provide another chance to develop measles immunity for people who did non answer to the first dose. Nigh 97% of people develop immunity to measles later two doses of measles-containing vaccine.

Are at that place any situations where more than 2 doses of MMR are recommended?

There are two circumstances when a 3rd dose of MMR is recommended. ACIP recommends that women of childbearing historic period who accept received ii doses of rubella-containing vaccine and have rubella serum IgG levels that are not conspicuously positive should receive 1 additional dose of MMR vaccine (maximum of 3 doses). Further testing for serologic evidence of rubella amnesty is not recommended. MMR should not be administered to a pregnant adult female.

In 2018, ACIP published guidance for MMR vaccination of people at increased risk for acquiring mumps during an outbreak. People previously vaccinated with 2 doses of a mumps virus�containing vaccine who are identified past public health regime as being function of a group or population at increased hazard for acquiring mumps considering of an outbreak should receive a third dose of a mumps virus�containing vaccine (MMR or MMRV) to improve protection against mumps affliction and related complications. More information about this recommendation is available at www.cdc.gov/mmwr/volumes/67/wr/pdfs/mm6701a7-H.pdf.

When is it appropriate to use MMR vaccine for measles post-exposure prophylaxis?

MMR vaccine given inside 72 hours of initial measles exposure can reduce the risk of getting sick or reduce the severity of symptoms. Some other pick for exposed, measles-susceptible individuals at loftier risk of complications who cannot be vaccinated is to give immunoglobulin (IG) inside six days of exposure. Do not administer MMR vaccine and IG simultaneously, as the IG invalidates the vaccine.

Information on mail service-exposure prophylaxis for measles tin can be plant in the 2013 ACIP guidance at www.cdc.gov/mmwr/pdf/rr/rr6204.pdf, page 24.

Do any adults demand "booster" doses of MMR vaccine to prevent measles?

No. Adults with show of immunity do not need any further vaccines. No "booster" doses of MMR vaccine are recommended for either adults or children. They are considered to have life-long immunity once they have received the recommended number of MMR vaccine doses or take other evidence of immunity.

Many people who were young children in the 1960s exercise not have records indicating what type of measles vaccine they received in the mid-1960s. What measles vaccine was most oft given in that time period? That guidance would assist many older people who would prefer not to be revaccinated.

Both killed and live adulterate measles vaccines became bachelor in 1963. Live adulterate vaccine was used more than oftentimes than killed vaccine. The killed vaccine was found to be not effective and people who received it should be revaccinated with live vaccine. Without a written record, it is not possible to know what type of vaccine an private may have received. So persons born during or after 1957 who received killed measles vaccine or measles vaccine of unknown type, or who cannot certificate having been vaccinated or having laboratory-confirmed measles affliction should receive at to the lowest degree i dose of MMR. Some people at increased run a risk of exposure to measles (such as healthcare professionals and international travelers) should receive 2 doses of MMR separated past at least iv weeks.

Do people who received MMR in the 1960s need to take their dose repeated?

Not necessarily. People who have documentation of receiving live measles vaccine in the 1960s do not need to be revaccinated. People who were vaccinated prior to 1968 with either inactivated (killed) measles vaccine or measles vaccine of unknown type should be revaccinated with at least one dose of live adulterate measles vaccine. This recommendation is intended to protect people who may accept received killed measles vaccine which was available in the United States in 1963 through 1967 and was not effective. People vaccinated before 1979 with either killed mumps vaccine or mumps vaccine of unknown blazon who are at high risk for mumps infection (such equally people who work in a healthcare facility) should be considered for revaccination with two doses of MMR vaccine.

I empathize that ACIP inverse its definition of evidence of immunity to measles, rubella, and mumps in 2013. Please explain.

In the 2013 revision of its MMR vaccine recommendations ACIP includes laboratory confirmation of disease every bit evidence of amnesty for measles, mumps, and rubella. ACIP removed physician diagnosis of disease as prove of amnesty for measles and mumps. Doctor diagnosis of illness had non previously been accepted as evidence of amnesty for rubella. With the decrease in measles and mumps cases over the terminal 30 years, the validity of physician-diagnosed affliction has go questionable. In improver, documenting history from physician records is not a practical option for well-nigh adults. The 2013 MMR ACIP recommendations are available at www.cdc.gov/mmwr/pdf/rr/rr6204.pdf.

Is at that place anything that tin can be done for unvaccinated people who accept already been exposed to measles, mumps, or rubella?

Measles vaccine, given as MMR, may be effective if given within the first 3 days (72 hours) after exposure to measles. Immune globulin may be effective for as long as vi days later exposure. Postexposure prophylaxis with MMR vaccine does not prevent or change the clinical severity of mumps or rubella. However, if the exposed person does not have evidence of mumps or rubella immunity they should exist vaccinated since non all exposures result in infection.

What are the current ACIP recommendations for use of immune globulin (IG) for measles, mumps, and rubella post-exposure prophylaxis?

In the 2013 revision of its MMR vaccine recommendations ACIP expanded the apply of post-exposure IG prophylaxis for measles. Intramuscular IG (IGIM) should be administered to all infants younger than 12 months who have been exposed to measles. The dose of IGIM is 0.5 mL/kg of trunk weight; the maximum dose is 15 mL. Alternatively, MMR vaccine can exist given instead of IGIM to infants historic period 6 through 11 months, if it can be given within 72 hours of exposure.

Pregnant women without prove of measles immunity who are exposed to measles should receive an intravenous IG (IGIV) dose of 400 mg/kg of body weight. Severely immunocompromised people, irrespective of evidence of measles immunity or vaccination, who accept been exposed to measles should receive an IGIV dose of 400 mg/kg of body weight.

For persons already receiving IGIV therapy, administration of at least 400 mg/kg trunk weight within three weeks before measles exposure should be sufficient to foreclose measles infection. For patients receiving subcutaneous immune globulin (IGSC) therapy, administration of at least 200 mg/kg body weight for 2 consecutive weeks before measles exposure should be sufficient.

Other people who do not have evidence of measles immunity can receive an IGIM dose of 0.5 mL/kg of body weight. Requite priority to people who were exposed to measles in settings where they have intense, prolonged close contact (such as household, child care, classroom, etc.). The maximum dose of IGIM is 15 mL.

IG is not indicated for persons who accept received 1 dose of measles-containing vaccine at historic period 12 months or older unless they are severely immunocompromised. IG should not be used to command measles outbreaks.

IG has not been shown to prevent mumps or rubella infection after exposure and is not recommended for that purpose.

We oft see college students who lack vaccination records, but whose titer results show they are non immune to some combination of measles, rubella, and/or mumps. What type of vaccine should these students receive?

Unmarried antigen vaccine is no longer available in the U.S.; the educatee should become the combined MMR vaccine. If a college student or other person at increased risk of exposure cannot produce written documentation of either immunization or disease, and titers are negative, they should receive ii doses of MMR.

I have patients who claim to recall receiving MMR vaccine but accept no written record, or whose parents study the patient has been vaccinated. Should I accept this every bit testify of vaccination?

No. Cocky-reported doses and history of vaccination provided by a parent or other caregiver are not considered to be valid. Yous should only accept a written, dated tape equally evidence of vaccination.

Nether what circumstances should adults be considered for testing for measles-specific antibody prior to getting vaccinated?

Adults without evidence of amnesty and no contraindications to MMR vaccine can exist vaccinated without testing. Only adults without testify of immunity might be considered for testing for measles-specific IgG antibiotic, simply testing is non needed prior to vaccination.

CDC does not recommend measles antibody testing after MMR vaccination to verify the patient'southward immune response to vaccination.

Two documented doses of MMR vaccine given on or after the first altogether and separated by at least 28 days is considered proof of measles immunity, co-ordinate to ACIP. Documentation of appropriate vaccination supersedes the results of serologic testing for measles, mumps, rubella, and varicella.

A patient born in 1970 has a history of measles disease and is too immunosuppressed due to multiple myeloma. The patient wants to travel to Africa, only is concerned about the measles exposure hazard. Should the patient receive the MMR vaccine?

A history of having had measles is not sufficient evidence of measles immunity. A positive serologic exam for measles-specific IgG will confirm that the person is immune and is not at risk of infection regardless of the multiple myeloma. Multiple myeloma is a hematologic cancer and is considered immunosuppressive so MMR vaccine is contraindicated in this person.

We take developed patients in our practice at high risk for measles, including patients going dorsum to college or preparing for international travel, who don't remember always receiving MMR vaccine or having had measles disease. How should nosotros manage these patients?

Y'all have ii options. You lot can test for immunity or you can only give 2 doses of MMR at to the lowest degree 4 weeks apart. There is no harm in giving MMR vaccine to a person who may already be immune to ane or more than of the vaccine viruses. If you or the patient opt for testing, and the tests indicate the patient is not immune to one or more than of the vaccine components, give your patient 2 doses of MMR at least 4 weeks apart. If whatsoever test results are indeterminate or equivocal, consider your patient nonimmune. ACIP does not recommend serologic testing after vaccination because commercial tests may non be sensitive enough to reliably detect vaccine-induced immunity.

I have a 45-yr-onetime patient who is traveling to Republic of haiti for a mission trip. She doesn't recall ever getting an MMR booster (she didn't go to college and never worked in health care). She was rubella immune when significant twenty years ago. Her measles titer is negative. Would you recommend an MMR booster?

ACIP recommends 2 doses of MMR given at least 4 weeks apart for whatever adult born in 1957 or later who plans to travel internationally. At that place is no harm in giving MMR vaccine to a person who may already be immune to i or more than of the vaccine viruses.

A patient who was born before 1957 and is non a healthcare worker wants to become the MMR vaccine before international travel. Does he need a dose of MMR?

No, it is not considered necessary, but he may be vaccinated. Earlier implementation of the national measles vaccination program in 1963, virtually every person acquired measles before adulthood. Then, this patient tin be considered immune based on their birth twelvemonth. However, MMR vaccine too may be given to any person born before 1957 who does not have a contraindication to MMR vaccination.

Routine testing of patients born before 1957 for measles-specific antibiotic is not recommended past CDC.

Nosotros have measles cases in our community. How can I best protect the young children in my practice?

First of all, brand sure all your patients are fully vaccinated according to the U.Southward. immunization schedule.

In certain circumstances, MMR is recommended for infants age 6 through eleven months. Give infants this age a dose of MMR before international travel. In addition, consider measles vaccination for infants every bit young every bit age 6 months equally a command measure out during a U.S. measles outbreak. Consult your country health department to discover out if this is recommended in your situation. Do non count any dose of MMR vaccine as part of the 2-dose series if information technology is administered before a kid's showtime altogether. Instead, repeat the dose when the child is age 12 months.

In the case of a local outbreak, y'all also might consider vaccinating children age 12 months and older at the minimum historic period (12 months, instead of 12 through fifteen months) and giving the second dose 4 weeks later on (at the minimum interval) instead of waiting until historic period four through 6 years.

Finally, think that infants too young for routine vaccination and people with medical weather condition that contraindicate measles immunization depend on high MMR vaccination coverage among those around them. Be sure to encourage all your patients and their family members to become vaccinated if they are not immune.

During a mumps outbreak should we offer a third dose of MMR (MMR II, Merck) to persons who take two prior documented doses of MMR?

In recent years, mumps outbreaks have occurred primarily in populations in institutional settings with close contact (such as residential colleges) or in close-knit social groups. The current routine recommendation for 2 doses of MMR vaccine appears to be sufficient for mumps control in the general population, simply bereft for preventing mumps outbreaks in prolonged, close-contact settings, fifty-fifty where coverage with 2 doses of MMR vaccine is high.

In Jan 2018, the Advisory Commission on Immunization Practices (ACIP) published new guidance for MMR vaccination of persons at increased take chances for acquiring mumps during an outbreak. Persons previously vaccinated with 2 doses of a mumps virus�containing vaccine who are identified by public wellness authorities every bit beingness part of a group at increased adventure for acquiring mumps because of an outbreak should receive a third dose of a mumps virus�containing vaccine to improve protection against mumps disease and related complications. More information almost this recommendation is available at www.cdc.gov/mmwr/volumes/67/wr/pdfs/mm6701a7-H.pdf.

In a measles outbreak, do children who have not had MMR vaccine pose a threat to vaccinated people? Information technology is my understanding that vaccinated people tin still contract measles. Am I right?

You are correct that vaccinated people tin can nonetheless be infected with viruses or bacteria against which they are vaccinated. No vaccine is 100% constructive. Vaccine effectiveness varies from greater than 95% (for diseases such as measles, rubella, and hepatitis B) to much lower (60% for influenza in years with a skillful match of circulating and vaccine viruses, and 70% for acellular pertussis vaccines in the iii-5 years subsequently vaccination). More information is available for each vaccine and disease at world wide web.cdc.gov/vaccines/vpd-vac/default.htm and www.immunize.org/vaccines.

Administering Vaccines Dorsum to top

Our dispensary has been giving MMR by the incorrect route (IM rather than SC) for years. Should these doses be repeated?

All live injected vaccines (MMR, varicella, and xanthous fever) are recommended to be given subcutaneously. However, intramuscular administration of any of these vaccines is not likely to decrease immunogenicity, and doses given IM do not need to be repeated.

We often need to requite MMR vaccine to large adults. Is a 25-gauge needle with a length of 5/8" sufficient for a subcutaneous injection?

Yeah. A 5/8" needle is recommended for subcutaneous injections for people of all sizes.

MMRV was mistakenly given to a 31-year-erstwhile instead of MMR. Can this be considered a valid dose?

Yes, nonetheless, this event is not addressed in the 2010 MMRV ACIP recommendations. Although this is off-label use, CDC recommends that when a dose of MMRV is inadvertently given to a patient age thirteen years and older, information technology may be counted towards completion of the MMR and varicella vaccine serial and does not need to be repeated.

Scheduling Vaccines Back to tiptop

How before long tin we give the 2nd dose of MMR vaccine to a child vaccinated at 12 months old?

For routine vaccination, children without contraindications to MMR vaccine should receive ii doses of MMR vaccine with the first dose at historic period 12–xv months old and the 2nd dose at historic period 4–6 years sometime. The minimum interval is 28 days for dose two. If you accept an outbreak in your community or a kid is traveling internationally, then consider using the minimum interval instead of waiting until age iv–6 years old for dose ii.

Does the four-day "grace period" apply to the minimum age for administration of the showtime dose of MMR? What about the 28-mean solar day minimum interval between doses of MMR?

A dose of MMR vaccine administered upwardly to four days before the start birthday may be counted every bit valid. Notwithstanding, schoolhouse entry requirements in some states may mandate administration on or afterwards the start birthday. The 4-day "grace period" should not be applied to the 28-twenty-four hour period minimum interval between 2 doses of a live parenteral vaccine.

Can MMR be given on the same day as other live virus vaccines?

Yeah. Notwithstanding, if two parenteral or intranasal live vaccines (MMR, varicella, LAIV and/or yellow fever) are not administered on the same day, they should be separated by an interval of at least 28 days.

If you can requite the second dose of MMR as early as 28 days after the first dose, why do we routinely wait until kindergarten entry to requite the second dose?

The second dose of MMR may exist given as early equally 4 weeks after the first dose, and be counted as a valid dose if both doses were given after the start birthday. The second dose is not a booster, but rather it is intended to produce immunity in the small number of people who fail to respond to the first dose. The risk of measles is higher in schoolhouse-age children than those of preschool age, so it is important to receive the second dose by school entry. It is also user-friendly to give the second dose at this historic period, since the child volition accept an immunization visit for other school entry vaccines.

What is the earliest age at which I can requite MMR to an infant who will be traveling internationally? Also, which countries pose a high gamble to children for contracting measles?

ACIP recommends that children who travel or live away should be vaccinated at an before age than that recommended for children who reside in the Usa. Before their departure from the U.s., children historic period 6 through 11 months should receive 1 dose of MMR. The take a chance for measles exposure tin can be high in high-, middle- and low-income countries. Consequently, CDC encourages all international travelers to be up to date on their immunizations regardless of their travel destination and to go along a copy of their immunization records with them every bit they travel. For additional information on the worldwide measles situation, and on CDC'due south measles vaccination data for travelers, go to wwwnc.cdc.gov/travel.

If we give a child a dose of MMR vaccine at six months of age because they are in a community with cases of measles, when should we requite the adjacent dose?

The next dose should be given at 12 months of age. The child will likewise need another dose at least 28 days subsequently. For the child to be fully vaccinated, they demand to have 2 doses of MMR vaccine given when the kid is 12 months of historic period and older. A dose given at less than 12 months of historic period does not count as part of the MMR vaccine ii-dose series.

I have an 8-month-sometime patient who is traveling internationally. The babe needs to be protected from hepatitis A also equally measles, mumps, and rubella. The family is leaving in eleven days. Can I requite hepatitis A IG and MMR vaccine simultaneously?

No. IG may contain antibodies to measles, mumps, and rubella that could reduce the effectiveness of MMR vaccine. For this reason, in February 2018 ACIP voted to recommend that hepatitis A vaccine should be administered to infants age six through 11 months traveling exterior the Us when protection against hepatitis A is recommended. MMR and hepatitis A vaccine may exist safely co-administered to children in this historic period group. Neither vaccine is counted equally function of the child'due south routine vaccination serial. For details of this recommendation, encounter the CDC ACIP recommendations for the prevention and command of hepatitis A at www.cdc.gov/mmwr/volumes/69/rr/pdfs/rr6905a1-H.pdf, folio 18.

Can I give the second dose of MMR earlier than age four through 6 years (the kindergarten entry dose) to young children traveling to areas of the earth where there are measles cases?

Aye. The 2d dose of MMR can be given a minimum of 28 days after the beginning dose if necessary.

If I give MMR to an infant traveler younger than age 1 year, will that dose be considered valid for the U.S. immunization schedule?

No. A measles-containing vaccine administered more than than 4 days before the first birthday should not be counted equally office of the series. MMR should be repeated when the child is historic period 12 through 15 months (12 months if the kid remains in an expanse where illness risk is loftier). The 2nd dose should be administered at to the lowest degree 28 days later the get-go dose.

Tin I give a tuberculin skin examination (TST) on the aforementioned day equally a dose of MMR vaccine?

Yes. A TST can exist applied before or on the same 24-hour interval that MMR vaccine is given. Even so, if MMR vaccine is given on the previous day or earlier, the TST should be delayed for at to the lowest degree 28 days. Alive measles vaccine given prior to the application of a TST can reduce the reactivity of the skin test because of mild suppression of the immune organisation.

An 18-twelvemonth-old higher student says he had both measles and mumps diseases as a preschooler, just never had MMR vaccine. Is rubella vaccine recommended in such a state of affairs?

This student should receive two doses of MMR, separated by at to the lowest degree 28 days. A personal history of measles and mumps is not acceptable as proof of immunity. Acceptable evidence of measles and mumps immunity includes a positive serologic exam for antibody, birth before 1957, or written documentation of vaccination. For rubella, merely serologic evidence or documented vaccination should be accepted as proof of immunity. Additionally, people born prior to 1957 may be considered allowed to rubella unless they are women who have the potential to become pregnant.

When non given on the aforementioned twenty-four hours, is the interval between yellowish fever and MMR vaccines 4 weeks (28 days) or 30 days? I have seen the yellowish fever and live virus vaccine recommendations published both ways.

The General Best Practice Guidelines for Immunization (run across www.cdc.gov/vaccines/hcp/acip-recs/general-recs/timing.html) makes the generic recommendation that live parenterally or nasally administered vaccines not given on the same mean solar day should be separated by at least 28 days. The CDC travel health website recommends that yellowish fever vaccine and other parenteral or nasal live vaccines should be separated by at to the lowest degree 30 days if possible. Either interval is acceptable.

For Healthcare Personnel Back to top

What is the recommendation for MMR vaccine for healthcare personnel?

ACIP recommends that all HCP born during or afterward 1957 have adequate presumptive bear witness of immunity to measles, mumps, and rubella, divers as documentation of ii doses of measles and mumps vaccine and at to the lowest degree one dose of rubella vaccine, laboratory evidence of immunity, or laboratory confirmation of disease. Further, ACIP recommends that healthcare facilities should consider vaccination of all unvaccinated healthcare personnel who were built-in before 1957 and who lack laboratory bear witness of measles, mumps, and/or rubella immunity or laboratory confirmation of disease. During an outbreak of measles or mumps, healthcare facilities should recommend two doses of MMR separated by at least iv weeks for unvaccinated healthcare personnel regardless of birth year who lack laboratory testify of measles or mumps amnesty or laboratory confirmation of disease. During outbreaks of rubella, healthcare facilities should recommend ane dose of MMR for unvaccinated personnel regardless of birth year who lack laboratory evidence of rubella immunity or laboratory confirmation of infection or disease.

Would you consider healthcare personnel with ii documented doses of MMR vaccine to be allowed even if their serology for 1 or more of the antigens comes back negative?

Yes. Healthcare personnel (HCP) with 2 documented doses of MMR vaccine are considered to exist immune regardless of the results of a subsequent serologic exam for measles, mumps, or rubella. Documented age-appropriate vaccination supersedes the results of subsequent serologic testing. In contrast, HCP who practice not accept documentation of MMR vaccination and whose serologic test is interpreted equally "indeterminate" or "equivocal" should be considered non immune and should receive ii doses of MMR vaccine (minimum interval 28 days). ACIP does not recommend serologic testing after vaccination. For more information, come across ACIP's recommendations on the use of MMR vaccine at www.cdc.gov/mmwr/pdf/rr/rr6204.pdf, page 22.

If a healthcare worker develops a rash and depression-course fever after MMR vaccine, is s/he infectious?

Approximately 5 to xv% of susceptible people who receive MMR vaccine will develop a low-form fever and/or mild rash vii to 12 days after vaccination. However, the person is not infectious, and no special precautions ( such every bit exclusion from work) demand to exist taken.

A 22-twelvemonth-old female is going to pharmacy school and the school wants her to have a 2d dose of MMR vaccine. She had the first dose as a child and developed measles within 24 hours of receiving the vaccine. Recent serologic testing showed she is immune to mumps and measles but not immune to rubella. Can I give her a second dose of the MMR with her having measles after the first dose?

Yes, equally a healthcare professional, this person should get a 2d dose of MMR to ensure she is immune to rubella. There is no harm in providing MMR to a person who is already immune to one or more of the components. If she developed measles only one day afterwards getting her first MMR, she must take been exposed to the affliction prior to vaccination.

Contraindications and Precautions Back to top

What are the contraindications and precautions for MMR vaccine?

Contraindications:

• history of a severe (anaphylactic) reaction to any vaccine component (e.m., neomycin) or following a previous dose of MMR • pregnancy • severe immunosuppression from either disease or therapy

Precautions:

• receipt of an antibiotic-containing blood product in the previous iii–11 months, depending on the type of claret product received. Run across world wide web.cdc.gov/vaccines/hcp/acip-recs/general-recs/timing.html, Tabular array three-5 for more data on this issue • moderate or severe acute illness with or without fever • history of thrombocytopenia or thrombocytopenic purpura • Important details about the contraindications and precautions for MMR vaccine are in the current MMR ACIP statement, bachelor at www.cdc.gov/mmwr/pdf/rr/rr6204.pdf.

Nosotros have many patients who are immunocompromised and cannot get the MMR vaccine. How should we advise our patients?

People with medical conditions that contraindicate measles immunization depend on loftier MMR vaccination coverage among those around them. To help forbid the spread of measles virus, make sure all your staff and patients who can be vaccinated are fully vaccinated according to the U.S. immunization schedule. Also, encourage patients to remind their family members and other close contacts to go vaccinated if they are not immune.

If patients who cannot get MMR vaccine are exposed to measles, CDC has guidelines for immune globulin for post-exposure prophylaxis which can be found at world wide web.cdc.gov/mmwr/pdf/rr/rr6204.pdf.

We have a patient who has selective IgA deficiency. Nosotros also have patients with selective IgM deficiency. Can MMR or varicella vaccine be administered to these patients?

There is no known take chances associated with MMR or varicella vaccination in someone with selective IgA or IgM deficiency. It is possible that the immune response may be weaker, but the vaccines are likely effective.

I have a patient who is traveling internationally and needs MMR vaccine. He recently received an injectable steroid. How long should he look before receiving MMR vaccine?

There is no need to look a specific interval before giving MMR. Injectable steroids are not considered immunosuppressive for the purpose of vaccination decisions, and then at that place is no concern about safety or efficacy of MMR.

Can I give MMR to a child whose sibling is receiving chemotherapy for leukemia?

Yes. MMR and varicella vaccines should be given to the healthy household contacts of immunosuppressed children.

Nosotros have a 40 lb six-year-old patient who has been taking 15 mg of methotrexate weekly for arthritis for 12 months. Tin we requite the child MMR and varicella vaccine based on this methotrexate dosage?

Based on the weight and dosage provided (40 lbs and 15 mg/calendar week), the child is currently receiving more than 0.4 mg/kg/calendar week of methotrexate. This meets the Infectious disease Society of America (IDSA) definition of high-level immunosuppression. Assistants of both varicella and MMR vaccines are contraindicated until such time as the methotrexate dosage can be reduced. The 2013 IDSA definition of low-level immunosuppression for methotrexate is a dosage of less than 0.4 mg/kg/week. For additional details, run into the 2013 IDSA Clinical Practice Guideline for Vaccination of the Immunocompromised Host: cid.oxfordjournals.org/content/early on/2013/xi/26/cid.cit684.full.pdf.

Is it truthful that egg allergy is non considered a contraindication to MMR vaccine?

Several studies accept documented the condom of measles and mumps vaccine (which are grown in chick embryo tissue culture) in children with severe egg allergy. Neither the American University of Pediatrics nor ACIP consider egg allergy as a contraindication to MMR vaccine. ACIP recommends routine vaccination of egg-allergic children without the use of special protocols or desensitization procedures.

Tin can I give MMR to a breastfeeding mother or to a breastfed infant?

Yes. Breastfeeding does non interfere with the response to MMR vaccine. Vaccination of a woman who is breastfeeding poses no take a chance to the infant existence breastfed. Although information technology is believed that rubella vaccine virus, in rare instances, may be transmitted via breast milk, the infection in the baby is asymptomatic.

If a patient recently received a blood product, can he or she receive MMR vaccine?

Yeah, just there should be sufficient time between the blood product and the MMR to reduce the risk of interference. The interval depends on the blood product received. Run into Table 3-five of ACIP's Full general Best Exercise Guidelines for Immunization for more information, available at www.cdc.gov/vaccines/hcp/acip-recs/general-recs/timing.html.

Is it acceptable practice to administer MMR, Tdap, and influenza vaccines to a postpartum mom at the aforementioned time as administering RhoGam?

Yes. Receipt of RhoGam is not a reason to delay vaccination. For more information see the ACIP Full general Best Practice Guidelines for Immunization, available at www.cdc.gov/vaccines/hcp/acip-recs/general-recs/timing.html.

Please draw the current ACIP recommendations for the use of MMR vaccine in people who are infected with HIV.

ACIP recommendations for vaccinating people with HIV infection were revised in 2013. The current recommendations are equally follows:

Administer 2 doses of MMR vaccine to all HIV-infected people age 12 months and older who practise not have evidence of current severe immunosuppression or electric current evidence of measles, rubella, and mumps immunity. To be regarded every bit not having evidence of current astringent immunosuppression, a child age v years or younger must accept CD4 percentages of 15% or more for half dozen months or longer; a person older than five years must accept CD4 percentages of 15% or more and a CD4 lymphocyte count of 200 or more/mm3 for 6 months or longer. If laboratory results state only one blazon of parameter (pct or counts) this is sufficient for vaccine decision-making.

Administer the get-go dose at 12 through xv months and the second dose to children historic period iv through 6 years, or every bit early equally 28 days afterward the first dose.

Unless they have acceptable electric current evidence of measles, mumps, and rubella immunity, people with perinatal HIV infection who were vaccinated prior to establishment of effective antiretroviral therapy (ART) should receive 2 appropriately spaced doses of MMR vaccine after constructive ART has been established. Established effective ART is divers equally receiving ART for at to the lowest degree six months in combination with CD4 percentages of xv% or more than for vi months or longer for children age 5 years or younger. People older than 5 years should have CD4 percentages of 15% or more and a CD4 lymphocyte count of 200 or more/mm3 for 6 months or longer. If laboratory results state only i blazon of parameter (percentages or counts) this is sufficient for vaccine decision-making.

Pregnancy and Postpartum Considerations Back to pinnacle

What is the recommended length of fourth dimension a woman should wait afterward receiving rubella (MMR) vaccine before becoming pregnant?

Although the MMR vaccine packet insert recommends a 3-month deferral of pregnancy later MMR vaccination, ACIP recommends deferral of pregnancy for iv weeks. For details on this issue, see ACIP's Control and Prevention of Rubella: Evaluation and Direction of Suspected Outbreaks, Rubella in Significant Women, and Surveillance for Built Rubella Syndrome.

How should teenage girls and women of child-bearing age be screened for pregnancy before MMR vaccination?

ACIP recommends that women of childbearing age be asked if they are currently pregnant or attempting to go pregnant. Vaccination should exist deferred for those who answer "yes." Those who reply "no" should be advised to avoid pregnancy for 4 weeks following vaccination. Pregnancy testing is not necessary.

If a meaning woman inadvertently receives MMR vaccine, how should she exist advised?

No specific action needs to be taken other than to reassure the woman that no adverse outcomes are expected as a result of this vaccination. MMR vaccination during pregnancy is not a reason to end the pregnancy. You should consult with others in your healthcare setting to place ways to foreclose such vaccination errors in the future. Detailed information near MMR vaccination in pregnancy is included in the most recent MMR ACIP statement, available at world wide web.cdc.gov/mmwr/pdf/rr/rr6204.pdf.

We require a pregnancy test for all our 7th graders before giving an MMR. Is this necessary?

No. ACIP recommends that women of childbearing age be asked if they are currently pregnant or attempting to go pregnant. Vaccination should be deferred for those who respond "yes." Those who reply "no" should be advised to avert pregnancy for 1 month following vaccination.

Can we give an MMR to a 15-month-old whose mother is 2 months pregnant?

Yes. Measles, mumps, and rubella vaccine viruses are not transmitted from the vaccinated person, so MMR vaccination of a household contact does not pose a take a chance to a meaning household member.

If a adult female'due south rubella examination outcome shows she is "not allowed" during a prenatal visit, simply she has ii documented doses of MMR vaccine, does she need a third dose of MMR vaccine postpartum?

In 2013, ACIP changed its recommendation for this situation (run into www.cdc.gov/mmwr/pdf/rr/rr6204.pdf, pages xviii–20). It is recommended that women of childbearing historic period who have received 1 or ii doses of rubella-containing vaccine and have rubella serum IgG levels that are non clearly positive should be administered 1 additional dose of MMR vaccine (maximum of 3 doses) and practice not demand to be retested for serologic evidence of rubella amnesty. MMR should not exist administered to a pregnant adult female.

I have a female person patient who has a non-immune rubella titer two months later her second MMR vaccination. Should she be revaccinated? If so, should the titer again be checked to decide seroconversion?

ACIP recommends that vaccinated women of childbearing age who accept received ane or ii doses of rubella-containing vaccine and take a rubella serum IgG levels that is non clearly positive should be administered i additional dose of MMR vaccine (maximum of three doses). Repeat serologic testing for evidence of rubella immunity is not recommended. Run across www.cdc.gov/mmwr/pdf/rr/rr6204.pdf, pages xviii–20, for more than information on this result.

MMR vaccines should non be administered to women known to be pregnant or attempting to get significant. Because of the theoretical risk to the fetus when the mother receives a alive virus vaccine, women should be counseled to avoid becoming pregnant for 28 days after receipt of MMR vaccine.

How presently after commitment can MMR be given to the female parent?

MMR can be administered any time after commitment. The vaccine should be administered to a woman who is susceptible to either measles, mumps, or rubella before hospital discharge, even if she has received RhoGam during the infirmary stay, leaves in less than 24 hours, or is breastfeeding.

Vaccine Safe Dorsum to superlative

Is there whatever evidence that MMR or thimerosal causes autism?

No. This result has been studied extensively, including a thorough review by the independent Found of Medicine (IOM). The IOM issued a report in 2004 that concluded in that location is no evidence supporting an association between MMR vaccine or thimerosal-containing vaccines and the development of autism. For more than information on thimerosal and vaccines in general, visit www.cdc.gov/vaccinesafety/Concerns/thimerosal/alphabetize.html.

A few parents are asking that their children receive separate components of the MMR vaccine because they fear MMR may exist linked to autism. What should I practise?

Merck no longer produces unmarried antigen measles, mumps, and/or rubella vaccines for the U.S. market place. Simply combined MMR is available. Y'all should educate parents about the lack of association between MMR and autism.

How likely is information technology for a person to develop arthritis from rubella vaccine?

Arthralgia (joint hurting) and transient arthritis (joint redness or swelling) following rubella vaccination occurs only in people who were susceptible to rubella at the fourth dimension of vaccination. Joint symptoms are uncommon in children and in adult males. Well-nigh 25% of non-immune mail-pubertal women report joint pain after receiving rubella vaccine, and well-nigh 10% to 30% report arthritis-like signs and symptoms.

When joint symptoms occur, they generally begin 1 to 3 weeks after vaccination, commonly are balmy and not incapacitating, last about ii days, and rarely recur.

Is there any impairment in giving an actress dose of MMR to a kid of age seven years whose record is lost and the mother is not sure about the concluding dose of MMR?

In general, although information technology is non ideal, receiving extra doses of vaccine poses no medical problem. However, receiving excessive doses of tetanus toxoid (eastward.g., DTaP, DT, Tdap, or Td) tin increase the take chances of a local adverse reaction. For details see the Actress Doses of Vaccine Antigens section of the ACIP General Best Practice Guidelines for Immunization at www.cdc.gov/vaccines/hcp/acip-recs/general-recs/timing.html.

Vaccination providers oft encounter people who do not have adequate documentation of vaccinations. Providers should merely have written, dated records as evidence of vaccination. With the exception of flu vaccine and pneumococcal polysaccharide vaccine, cocky-reported doses of vaccine without written documentation should non be accepted. An try to locate missing records should be made whenever possible by contacting previous healthcare providers, reviewing state or local immunization information systems, and searching for a personally held record.

If records cannot be located or will definitely not exist available anywhere because of the patient'southward circumstances, children without adequate documentation should be considered susceptible and should receive age-appropriate vaccination. Serologic testing for immunity is an alternative to vaccination for sure antigens (e.g., measles, rubella, hepatitis A, diphtheria, and tetanus).

Storage and Handling Back to height

How long can reconstituted MMR vaccine be stored in a refrigerator before information technology must be discarded?

The amount of time in which a dose of vaccine must exist used after reconstitution varies by vaccine and is ordinarily outlined somewhere in the vaccine's package insert. MMR must be used within 8 hours of reconstitution. MMRV must be used inside xxx minutes; other vaccines must exist used immediately. The Immunization Action Coalition has a staff didactics slice that outlines the time allowed between reconstitution and use, equally stated in the parcel inserts for a number of vaccines. Handout tin be found at the following link: www.immunize.org/catg.d/p3040.pdf.

How should MMR vaccine be stored?

MMR may be stored either in the refrigerator at ii°C to eight°C (36°F to 46°F) or in the freezer at -fifty°C to -15°C (-58°F to +5°F). The diluent should not be frozen and can be stored in the refrigerator or at room temperature.

If the MMR is combined with varicella vaccine every bit MMRV (ProQuad, Merck), information technology must exist stored in the freezer at -50°C to -xv°C (-58°F to +five°F).

A box of MMR vaccine (non reconstituted) was left at room temperature overnight. Can I use information technology?

Unfortunately, serious errors in vaccine storage and treatment like this occur too ofttimes. If you suspect that vaccine has been mishandled, you should shop the vaccine equally recommended, and then contact the manufacturer or land/local wellness department for guidance on its use. This is especially important for live virus vaccines similar MMR and varicella.

One time MMR vaccine has been reconstituted with diluent, how soon must it be used?

It is preferable to administer MMR immediately after reconstitution. If reconstituted MMR is not used within 8 hours, it must be discarded. MMR should always be refrigerated and should never be left at room temperature.

I misplaced the diluent for the MMR dose so I used normal saline instead. Is there any problem with doing this?

Merely the diluent supplied with the vaccine should be used to reconstitute whatsoever vaccine. Any vaccine reconstituted with the incorrect diluent should exist repeated.
