Protection against diphtheria, tetanus, whooping cough and polio can fade over time. Also, immunity to measles, mumps and rubella may not develop after a single dose of the MMR vaccine.
The immunisations offered from age 3 years 4 months – often called pre-school boosters – will top up your child’s level of antibodies (the substances our bodies produce to fight off disease and infection) and help to keep them protected.
Immunisations from 3 years 4 months:
Helps protect against diphtheria, tetanus, pertussis (whooping cough) and polio.
Helps protect against measles, mumps and rubella.
All children aged 2 and older are offered a nasal spray flu vaccine every year.
