Please reevaluate your child's vaccination records to make sure you are up to date. The MMR is a tremendously effective, safe vaccine.
Your child will need 2 shots to have full immunity. The usual recommendation is 1st shot at age 12 months, second shot age 4-6yrs old, but can be earlier.
In case of an outbreak or foreign travel, you can do first shot at age 6mo.
