7-12 days: The MMR (measles-mumps-rubella) vaccine is typically given at 12 months of age and prior to kindergarten entry. About 5% of recipients may have a mild rash and/or fever about 7-12 days following administration of the vaccine. The rash and fever are self-limited, resolving on their own.
Created for people with ongoing healthcare needs but benefits everyone.
