Prevention of Measles
The best way to protect your kids is to make sure they're immunized against measles.
For most kids, measles protection is part of the measles-mumps-rubella vaccine (MMR) or measles-mumps-rubella-varicella vaccine (MMRV) given when they're 12 to 15 months old and again when they're 4 to 6 years old.
It's important for all kids who can get the vaccine to get it on schedule. At-risk people (such as those with weakened immune systems) can't get the vaccine and depend on "herd immunity." This is when a lot of people are immunized against a disease, which prevents it from spreading and helps prevent outbreaks.
