Question

My child is 11 years old and received the measles, rubella, and mumps combined vaccine last spring. This year, the county is implementing a measles and rubella prevention campaign. I would like to know if my child needs to be revaccinated to prevent the common mumps during spring?

Answer

The measles, rubella, and mumps combined vaccine (measles-rubella-mumps vaccine) can simultaneously prevent measles, rubella, and epidemic parotitis. For children aged 1 to 14 years old, a single dose can provide long-term immunity. Generally, it is not recommended to revaccinate in the short term because the antibodies produced by the vaccine can last for many years. In your child’s case, if effective immunity has been established after vaccination, there is no need for revaccination at such a short interval.
