What kind of “evidence of immunity” can substi-
tute for MMR vaccination?
Evidence of immunity can be shown by having labo-
ratory evidence of immunity to measles, mumps,
and/or rubella or laboratory confirmation of disease.
However, if a person doesn’t have evidence of
immunity to all three diseases (e.g., measles, mumps,
and rubella), they would still need to get vaccinated
with MMR since the vaccine is not available as a
single antigen product in the U.S.
At what age should MMR be given?
The first dose of MMR should be given at 12–15
months. The second dose is usually given at age 4–6
years but can be given earlier as long as it has been
at least 28 days since the first dose.The first dose of
MMR should be given on or after the child’s first
birthday; the recommended age range is from 12–15
months. A dose given before 12 months of age will
not be counted, so the child’s medical appointment
should be scheduled with this in mind.
