At what age are haemophilus influenza type b and measles mumps rubella vaccines given?

The Haemophilus influenzae type b (Hib) vaccine is typically administered to children at around 15 months of age, as part of the routine immunization schedule in many countries, including New Zealand. This timing is important because by this age, infants have begun to lose their maternal antibodies, and they need active immunization to protect them against serious infections caused by Hib, such as meningitis or pneumonia.

The measles, mumps, and rubella (MMR) vaccine is also given at around 15 months of age for similar reasons. Administering these vaccines at this age ensures that children develop an adequate immune response to protect against these diseases, which can have serious health implications.

This vaccination schedule is designed to provide the best protection for children when they are most vulnerable and to ensure community immunity against these contagious diseases. Therefore, the choice of 15 months is aligned with established public health guidelines for childhood vaccinations.
