An 18-year-old enrolling in college says he had measles but never had MMR vaccine. Is that acceptable proof of immunity? [Video]
This student should receive two doses of MMR, separated by at least 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 test for antibody, birth before 1957, or written documentation of vaccination. For rubella, only serologic evidence or documented vaccination should be accepted as proof of immunity. Additionally, people born prior to 1957 may be considered immune to rubella unless they are women who have the potential to become pregnant.
