What is the recommended spacing between doses of the measles vaccine?

The recommended spacing between doses of the measles vaccine is typically 6 months. This schedule applies to both the measles, mumps, and rubella (MMR) vaccine as well as the measles, mumps, rubella, and varicella (MMRV) vaccine. The first dose is usually given to children between 12 and 15 months of age, and the second dose is administered between 4 and 6 years of age, or at least 28 days after the first dose. If the second dose is given earlier, the minimum interval of 6 months is essential to ensure proper immunity development.

It’s important to adhere to this recommended spacing to ensure that the immune system has adequate time to mount a response to the initial dose before being challenged again with the second dose. This timing helps to optimize vaccine efficacy, allowing children to achieve the best possible immunity against measles.

Spacing shorter than the recommended interval might not provide sufficient time for the immune response to properly strengthen, which could leave a child less protected against the disease. Thus, the answer pertains to the established guidelines in vaccination protocols to promote effective immunity.
