At what ages is the MMR vaccine administered?

The MMR (measles, mumps, and rubella) vaccine is typically administered in two doses as part of standard childhood immunization schedules. The first dose is given between 12 to 15 months of age, and a second dose is administered at the age of 4 to 6 years. This schedule is designed to provide immunity against these diseases at a time when children are at higher risk of exposure and when the effectiveness of the vaccine can be maximized.

By following this schedule, the vaccine helps reduce the incidence of these potentially serious infections in children, ensuring that they are protected as they enter school and social environments where these illnesses can spread more easily. Providing vaccinations at these specified ages also aligns with guidelines set by health authorities, helping to maintain public health through herd immunity.
