Can I get the measles if I have already been vaccinated?
Answer by James M. Steckelberg, M. D.
It is possible, but unlikely. The combination of measles-mumps-rubella (MMR) is a two-dose vaccine series that protects against measles, mumps and rubella. More than 93 percent of people who receive the first dose of MMR develop immunity to measles. After the second dose, 97 percent of people are protected.
The first dose of the MMR vaccine is recommended for children 12 months to 15 months of age. The second dose, which can be given as early as four weeks after the first dose, is recommended before your child begins at the age of 4 or 5 years in kindergarten or first grade or at the age of 1
When you grow up, talk to your doctor about whether or not you need the MMR vaccine. A blood test can confirm if you are immune.
The combined measles-mumps-rubella varicella vaccine (MMRV) is another option that also protects against chickenpox (varicella). It is a single shot that can be used instead of the MMR and chickenpox vaccines. Talk to your doctor about both options.
