Your doc might just suggest getting another dose of the MMR vaccine even if your titers aren’t checked just to ensure you’re boosted and protected.
In 2024, 40% of people who got measles in the U.S. were hospitalized. At least 1 died this year.
It's not worth not knowing. Make sure you're protected.
