@overholt “CDC does not recommend people who meet these criteria to be vaccinated with MMR even if they have a negative or equivocal result for a measles IgG test. Documented age-appropriate vaccination supersedes the results of subsequent serologic testing. However, if the person tested is a woman of reproductive age and could become pregnant and has a negative or equivocal titer for rubella, they should get a third dose of MMR.

PSA: I’m turning 55 next month, and there’s an issue with people who got vaccinated for measles around the same time I did as a kid having waning immunity. -
PSA: I’m turning 55 next month, and there’s an issue with people who got vaccinated for measles around the same time I did as a kid having waning immunity.@overholt I attended a clinician CDC webinar update on measles on 9/11/25 and asked this titer question specifically. The CDC response was: “CDC considers most people with documentation of 2 doses of MMR received after 12 months of age, and separated by at least 28 days, to have evidence of measles immunity…” 1/2

PSA: I’m turning 55 next month, and there’s an issue with people who got vaccinated for measles around the same time I did as a kid having waning immunity.@overholt I am reading responses to this thread and would like to refer people to the CDC website on FAQs regarding whether or not adults need more than 2 MMR vaccines. Most adults do not need more than 2 MMR vaccines and titers are NOT recommended. The exception is for adults vaccinated with the killed vaccine between 1963 and 1967: https://www.cdc.gov/measles/hcp/clinical-overview/questions.html
