What is the recommended schedule for the MMR vaccine?

The MMR (measles, mumps, and rubella) vaccine is recommended to be administered to children at 12 to 15 months of age as part of their routine immunization schedule. This timing is crucial because it is before the child is likely to be exposed to these diseases, and it allows the immune system to respond appropriately. The first dose helps to ensure that the child develops immunity to these potentially serious illnesses during the early years when they are most at risk.

Additionally, the CDC recommends a second dose of the MMR vaccine to be given between 4 to 6 years of age, which helps to boost immunity and protect against outbreaks.

Other options provided do not align with the established immunization schedule for the MMR vaccine. Administering the vaccine at 6 weeks would be too early for the infant’s immune system to mount an effective response. Similarly, the suggested ages of 14-18 months and 18-24 months fall outside the recommended guidelines for the first dose, as the initial vaccination should ideally occur between 12 and 15 months. Understanding the correct schedule is important for ensuring adequate protection against measles, mumps, and rubella.
