The following measles vaccine recommendations should be utilized for
residents and travelers to Hill County.
Infants Less than 6 months old:
Infants less than 6 months old are not recommended to receive a dose of MMR.
Infants 6 – 11 months:
Infants aged 6 – 11 months old are recommended to receive a dose of MMR vaccine
Early due to potential risk of ongoing measles transmission in Hill County MT. Measles,
Mumps, Rubella, and Varicella (MMRV) vaccine should not be utilized in infants under 12
months of age. Children who receive a dose of MMR prior to 12 months should still receive two
age-appropriate doses of MMR vaccine at least 28 days apart after their first birthday.
Children 12 months – 17 years:
Any child 12 months – 17 years old who have not previously received any dose of MMR
vaccine should be vaccinated immediately. For children residing in or visiting Hill County, a
second dose of MMR vaccine should be administered at least 28 days after receipt of the first
dose of MMR vaccine. Children residing in or visiting Hill County who received their first age
appropriate dose of MMR vaccine should not wait to receive their second dose of MMR vaccine
until 4-6 years old. The minimum interval of 28 days should be utilized due to the risk of
ongoing measles transmission in Hill County. No additional or booster doses of MMR are
recommended for children aged 1 – 17 years who have received two doses of MMR after 12
months old.
Adults 18 years and older:
All adults born before 1957 were likely exposed to measles as a child and considered
immune to measles. Unless these individuals work in health care, there are no recommendations
for these individuals to receive MMR vaccine.
Adults born between 1957 and 1968 who have no documented doses of MMR vaccine or who
received doses of inactivated MMR vaccine and who reside in or are visiting Hill County should
receive the first dose of MMR vaccine immediately followed by a second dose at least 28 days
later. Adults born in this age group who have one dose of live-attenuated MMR vaccine and who
reside in or are visiting Hill County should receive a second dose of MMR vaccine. There are no
booster or additional doses recommended after an individual has received two doses of MMR
vaccine.
Adults born after 1968 who reside in or are visiting Hill County and are unvaccinated should
receive a dose of MMR vaccine immediately followed by a second dose at least 28 days later.
Any adult born after 1968 residing in or visiting Hill County who has one documented dose of
MMR vaccine should receive a second dose of MMR vaccine. There are no booster or additional
doses recommended after an individual has received two doses of MMR vaccine. Adults born
after 1968 who DO NOT reside in or travel to Hill County only need one dose of MMR vaccine
to be considered up-to-date.

Anyone who does not know their vaccination status or is unable to find their record may
receive a dose of MMR.
