Plunket is encouraging parents to immunise their children after fears over a measles outbreak. Clinical adviser Allison Jamieson says immunisation is the most effective way to protect kids from childhood diseases. ‘‘‘Immunisation has a profoundly positive effect not only on the individual but on the whole of the population thereby improving community immunity from the disease,’’ she says. Immunisation is free and protects children against 11 serious diseases, including measles, mumps and rubella. Children can catch up on their immunisation schedule if they have fallen behind.
