Home / Ask The Experts / I have a 45-year-old patient who is traveling to 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 pregnant 20 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 any adult born in 1957 or later who plans to travel internationally. There is no harm in giving MMR vaccine to a person who may already be immune to one or more of the vaccine viruses.
