*Some states require a specified number of doses of each antigen (e.g., 2 doses of mumps-contining vaccine, 2 doses of measles-containing vaccine, and 1 dose of rubella-containing vaccine). Because only MMR vaccine is available in the U.S., most children would need 2 doses of MMR vaccine to meet the requirement. Contact state health department for details.
**WA – Children age 4 years on 9/01 of the school year attending preschool or transitional kindergarten must have 2 doses
