FULL PRESCRIBING INFORMATION
1 INDICATIONS AND USAGE
M-M-R® II is a vaccine indicated for active immunization for the prevention of measles, mumps, and
rubella in individuals 12 months of age and older.
2 DOSAGE AND ADMINISTRATION
For subcutaneous use only.
2.1 Dose and Schedule
Each 0.5 mL dose is administered subcutaneously.
The first dose is administered at 12 to 15 months of age. A second dose is administered at 4 to 6
years of age.
The second dose may be administered prior to 4 years of age, provided that there is a minimum
interval of one month between the doses of measles, mumps and rubella virus vaccine, live {1-2}.
Children who received an initial dose of measles, mumps and rubella vaccine prior to their first
birthday should receive additional doses of vaccine at 12-15 months of age and at 4-6 years of age to
complete the vaccination series [see Clinical Studies (14.2)].
For post-exposure prophylaxis for measles, administer a dose of M-M-R II vaccine within 72 hours
after exposure.
2.2 Preparation and Administration
Use a sterile syringe free of preservatives, antiseptics, and detergents for each injection and/or
reconstitution of the vaccine because these substances may inactivate the live virus vaccine. To
reconstitute, use only the diluent supplied with the vaccine since it is free of preservatives or other
antiviral substances which might inactivate the vaccine.
Withdraw the entire volume of the supplied diluent from its vial and inject into lyophilized vaccine vial.
Agitate to dissolve completely. Discard if the lyophilized vaccine cannot be dissolved.
Withdraw the entire volume of the reconstituted vaccine and inject subcutaneously into the outer
aspect of the upper arm (deltoid region) or into the higher anterolateral area of the thigh.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to
administration, whenever solution and container permit. Visually inspect the vaccine before and after
reconstitution prior to administration. Before reconstitution, the lyophilized vaccine is a light yellow
compact crystalline plug, when reconstituted, is a clear yellow liquid. Discard if particulate matter or
discoloration are observed in the reconstituted vaccine.
To minimize loss of potency, administer M-M-R II as soon as possible after reconstitution. If not used
immediately, the reconstituted vaccine may be stored between 36°F to 46°F (2°C to 8°C), protected from
light, for up to 8 hours. Discard reconstituted vaccine if it is not used within 8 hours.
3 DOSAGE FORMS AND STRENGTHS
M-M-R II vaccine is a suspension for injection supplied as a single dose vial of lyophilized vaccine to
be reconstituted using the accompanying sterile diluent [see Dosage and Administration (2.2) and How
Supplied/Storage and Handling (16)]. A single dose after reconstitution is 0.5 mL.
4 CONTRAINDICATIONS
4.1 Hypersensitivity
Do not administer M-M-R II vaccine to individuals with a history of hypersensitivity to any component
of the vaccine (including gelatin) {3} or who have experienced a hypersensitivity reaction following
administration of a previous dose of M-M-R II vaccine or any other measles, mumps and rubellacontaining vaccine. Do not administer M-M-R II vaccine to individuals with a history of anaphylaxis to
neomycin [see Description (11)].
4.2 Immunosuppression
Do not administer M-M-R II vaccine to individuals who are immunodeficient or immunosuppressed due
to disease or medical therapy. Measles inclusion body encephalitis {4} (MIBE), pneumonitis {5} and death
as a direct consequence of disseminated measles vaccine virus infection have been reported in
3
immunocompromised individuals inadvertently vaccinated with measles-containing vaccine. In this
population, disseminated mumps and rubella vaccine virus infection have also been reported.
Do not administer M-M-R II to individuals with a family history of congenital or hereditary
immunodeficiency, until the immune competence of the potential vaccine recipient is demonstrated.
4.3 Moderate or Severe Febrile Illness
Do not administer M-M-R II vaccine to individuals with an active febrile illness with fever >101.3F
(>38.5C).
4.4 Active Untreated Tuberculosis
Do not administer M-M-R II vaccine to individuals with active untreated tuberculosis (TB).
4.5 Pregnancy
Do not administer M-M-R II to individuals who are pregnant or who are planning on becoming
pregnant within the next month [see Use in Specific Populations (8.1) and Patient Counseling Information
(17)].
5 WARNINGS AND PRECAUTIONS
5.1 Febrile Seizure
There is a risk of fever and associated febrile seizure in the first 2 weeks following immunization with
M-M-R II vaccine. For children who have experienced a previous febrile seizure (from any cause) and
those with a family history of febrile seizures there is a small increase in risk of febrile seizure following
receipt of M-M-R II vaccine [see Adverse Reactions (6)].
5.2 Hypersensitivity to Eggs
Individuals with a history of anaphylactic, anaphylactoid, or other immediate reactions (e.g., hives,
swelling of the mouth and throat, difficulty breathing, hypotension, or shock) subsequent to egg ingestion
may be at an enhanced risk of immediate-type hypersensitivity reactions after receiving M-M-R II vaccine
.The potential risks and known benefits should be evaluated before considering vaccination in these
individuals.
5.3 Thrombocytopenia
Transient thrombocytopenia has been reported within 4-6 weeks following vaccination with measles,
mumps and rubella vaccine. Carefully evaluate the potential risk and benefit of vaccination in children
with thrombocytopenia or in those who experienced thrombocytopenia after vaccination with a previous
dose of measles, mumps, and rubella vaccine {6-8} [see Adverse Reactions (6)].
5.4 Immune Globulins and Transfusions
Immune Globulins (IG) and other blood products should not be given concurrently with M-M-R II [see
Drug Interactions (7.2)]. These products may contain antibodies that interfere with vaccine virus
replication and decrease the expected immune response.
The ACIP has specific recommendations for intervals between administration of antibody containing
products and live virus vaccines.

7 DRUG INTERACTIONS
7.1 Corticosteroids and Immunosuppressive Drugs
M-M-R II vaccine should not be administered to individuals receiving immunosuppressive therapy,
including high dose corticosteroids. Vaccination with M-M-R II vaccine can result in disseminated disease
due to measles vaccine in individuals on immunosuppressive drugs [see Contraindications (4.2)].
7.2 Immune Globulinsand Transfusions
Administration of immune globulins and other blood products concurrently with M-M-R II vaccine may
interfere with the expected immune response {9-11} [see Warnings and Precautions (5.4)]. The ACIP has
specific recommendations for intervals between administration of antibody containing products and live
virus vaccines.
7.3 Tuberculin Skin Testing
It has been reported that live attenuated measles, mumps and rubella virus vaccines given individually
may result in a temporary depression of tuberculin skin sensitivity. Therefore, if a tuberculin skin test with
tuberculin purified protein derivative (PPD) is to be done, it should be administered before, simultaneously
with, or at least 4 to 6 weeks after vaccination with M-M-R II vaccine.
7.4 Use with Other Live Viral Vaccines
M-M-R II vaccine can be administered concurrently with other live viral vaccines. If not given
concurrently, M-M-R II vaccine should be given one month before or one month after administration of
other live viral vaccines to avoid potential for immune interference.
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Risk Summary
M-M-R II vaccine is contraindicated for use in pregnant women because infection during pregnancy
with the wild-type viruses has been associated with maternal and fetal adverse outcomes.
Increased rates of spontaneous abortion, stillbirth, premature delivery and congenital defects have
been observed following infection with wild-type measles during pregnancy. {12,13} Wild-type mumps
infection during the first trimester of pregnancy may increase the rate of spontaneous abortion.
Infection with wild-type rubella during pregnancy can lead to miscarriage or stillbirth. If rubella infection
occurs during the first trimester of pregnancy, it can result in severe congenital defects, Congenital
Rubella Syndrome (CRS). Congenital rubella syndrome in the infant includes but is not limited to eye
manifestations (cataracts, glaucoma, retinitis), congenital heart defects, hearing loss, microcephaly, and
intellectual disabilities. M-M-R II vaccine contains live attenuated measles, mumps and rubella viruses. It
is not known whether M-M-R II vaccine can cause fetal harm when administered to pregnant woman.
There are no adequate and well-controlled studies of M-M-R II vaccine administration to pregnant
women.
5
All pregnancies have a risk of birth defect, loss or other adverse outcomes. In the US general
population, the estimated background risk of major birth defects and miscarriage in clinically recognized
pregnancies is 2% to 4% and 15% to 20%, respectively.
Available data suggest the rates of major birth defects and miscarriage in women who received
M-M-R II vaccine within 30 days prior to pregnancy or during pregnancy are consistent with estimated
background rates (see Data).
Data
Human Data
A cumulative assessment of post-marketing reports for M-M-R II vaccine from licensure 01 April 1978
through 31 December 2018, identified 796 reports of inadvertent administration of M-M-R II vaccine
occurring 30 days before or at any time during pregnancy with known pregnancy outcomes. Of the
prospectively followed pregnancies for whom the timing of M-M-R II vaccination was known, 425 women
received M-M-R II vaccine during the 30 days prior to conception through the second trimester. The
outcomes for these 425 prospectively followed pregnancies included 16 infants with major birth defects, 4
cases of fetal death and 50 cases of miscarriage. No abnormalities compatible with congenital rubella
syndrome have been identified in patients who received M-M-R II vaccine. Rubella vaccine viruses can
cross the placenta, leading to asymptomatic infection of the fetus. Mumps vaccine virus has also been
shown to infect the placenta {14}, but there is no evidence that it causes congenital malformations or
disease in the fetus or infant .
The CDC established the Vaccine in Pregnancy registry (1971-1989) of women who had received
rubella vaccines within 3 months before or after conception. Data on 1221 inadvertently vaccinated
pregnant women demonstrated no evidence of an increase in fetal abnormalities or cases of Congenital
Rubella Syndrome (CRS) in the enrolled women {15}.
8.2 Lactation
Risk Summary
It is not known whether measles or mumps vaccine virus is secreted in human milk. Studies have
shown that lactatingpostpartum women vaccinated with live attenuated rubella vaccine may secrete the
virus in breast milk and transmit it to breast-fed infants.{16,17} In the breast-fed infants with serological
evidence of rubella virus vaccine strain antibodies, none exhibited severe disease; however, one
exhibited mild clinical illness typical of acquired rubella.{18,19}
The developmental and health benefits of breastfeeding should be considered along with the mother’s
clinical need for M-M-R II, and any potential adverse effects on the breastfed child from M-M-R II or from
the underlying maternal condition. For preventive vaccines, the underlying maternal condition is
susceptibility to disease prevented by the vaccine.
8.4 Pediatric Use
M-M-R II vaccine is not approved for individuals less than 12 months of age. Safety and effectiveness
of measles vaccine in infants below the age of 6 months have not been established [see Clinical Studies
(14)]. Safety and effectiveness of mumps and rubella vaccine in infants less than 12 months of age have
not been established.
8.5 Geriatric Use
Clinical studies of M-M-R II did not include sufficient numbers of seronegative subjects aged 65 and
over to determine whether they respond differently from younger subjects.
11 Description
M-M-R II vaccine is a sterile lyophilized preparation of (1) Measles Virus Vaccine Live, an attenuated
line of measles virus, derived from Enders' attenuated Edmonston strain and propagated in chick embryo
cell culture; (2) Mumps Virus Vaccine Live, the Jeryl Lynn™ (B level) strain of mumps virus propagated in
chick embryo cell culture; and (3) Rubella Virus Vaccine Live, the Wistar RA 27/3 strain of live attenuated
rubella virus propagated in WI-38 human diploid lung fibroblasts. {20,21} The cells, virus pools,
recombinant human serum albumin and fetal bovine serum used in manufacturing are tested and
determined to be free of adventitious agents.
After reconstitution, each 0.5 mL dose contains not less than 3.0 log10 TCID50 (tissue culture infectious
doses) of measles virus; 4.1 log10 TCID50 of mumps virus; and 3.0 log10 TCID50 of rubella virus.
Each dose is calculated to contain sorbitol (14.5 mg), sucrose(1.9 mg), hydrolyzed gelatin (14.5 mg),
recombinant human albumin (≤0.3 mg), fetal bovine serum (<1 ppm), approximately 25 mcg of neomycin
and other buffer and media ingredients. The product contains no preservative.

12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
M-M-R II vaccination induces antibodies to measles, mumps, and rubella associated with protection
which can be measured by neutralization assays, hemagglutination-inhibition (HI) assays, or enzyme
linked immunosorbent assay (ELISA) tests. Results from efficacy studies or effectivenes s studies that
were previously conducted for the component vaccines of M-M-R II were used to define levels of serum
antibodies that correlated with protection against measles, mumps, and rubella [see Clinical Studies (14)].
12.6 Persistence of Antibody Responses After Vaccination
Neutralizing and ELISA antibodies to measles, mumps, and rubella viruses are still detectable in 95-
100%, 74-91%, and 90-100% of individuals respectively, 11 to 13 years after primary vaccination. {22-28}
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
M-M-R II vaccine has not been evaluated for carcinogenic or mutagenic potential or impairment of
fertility.
14 CLINICAL STUDIES
14.1 Clinical Efficacy
Efficacy of measles, mumps, and rubella vaccines was established in a series of double-blind
controlled trials. {29-34} These studies also established that seroconversion in response to vaccination
against measles, mumps and rubella paralleled protection. {35-38}
14.2 Immunogenicity
Clinical studies enrolling 284 triple seronegative children, 11 months to 7 years of age, demonstrated
that M-M-R II vaccine is immunogenic. In these studies, a single injection of the vaccine induced measles
HI antibodies in 95%, mumps neutralizing antibodies in 96%, and rubella HI antibodies in 99% of
susceptible individuals.
A study of 6-month-old and 15-month-old infants born to mothers vaccinated with a measles vaccine in
childhood, demonstrated that, following infant and toddler vaccination with Measles Virus Vaccine, Live
(previously US-licensed, manufactured by Merck), 74% of the 6-month-old infants developed detectable
neutralizing antibody titers while 100% of the 15-month-old infants vaccinated with Measles Virus
Vaccine, Live or M-M-R II vaccine developed neutralizing antibodies {39}. When the 6-month-old infants
of immunized mothers were revaccinated at 15 months with M-M-R II vaccine, they developed antibody
titers similar to those of toddlers who were vaccinated previously at 15-months of age.

Discuss the following with the patient:
• Provide the required vaccine information to the patient, parent, or guardian.
• Inform the patient, parent, or guardian of the benefits and risks associated with vaccination.
• Question the patient, parent, or guardian about reactions to a previous dose of M-M-R II vaccine
or other measles-, mumps-, or rubella-containing vaccines.
• Question females of reproductive potential regarding the possibility of pregnancy. Inform female
patients to avoid pregnancy for 1 month following vaccination [see Contraindications (4.5) and

Adverse Event Reporting System (VAERS) to accept all reports of suspected adverse events
after the administration of any vaccine, including but not limited to the reporting of events required
by the National Childhood Vaccine Injury Act of 1986. For information or a copy of the vaccine
reporting form, call the VAERS toll-free number at 1-800-822-7967, or report online at
