Your baby’s immune system is not fully developed like older children and adults. Therefore, vaccination is an effective way to protect your baby against certain vaccine-preventable infectious diseases.
By keeping your child up to date with their vaccinations, you’re also helping out the community by protecting the more vulnerable people from becoming infected. Many of the diseases we are vaccinating against are rarely seen in Australia anymore, which is because of routine widespread vaccination and surveillance. These diseases do still occur in some parts of the world. If we stopped vaccination and someone was to arrive from overseas with one of these infections, it could easily spread to others.
