Whether you should consider a booster varies depending on when you were born.
| Pre-1957 | If you were born before the measles vaccine became widely available, you likely had the virus as a child and are probably immune. Ask your doctor for a blood test to confirm. |
|---|---|
| 1957 - 1967 | You may still have had measles as a kid, but you should consider getting one or two doses of the current MMR vaccine because versions given during this time were less effective. |
| 1968 - 1989 | Back then, getting one dose was standard, rather than the current two. Ask your doctor for an antibodies test and consider a booster if you lack immunity. |
| After 1989 | If you had the two-dose MMR vaccine as recommended, you are likely well-protected without needing a booster. |
