Can a child's immune system be overloaded by immunisations? The answer is no. Its important to talk to a qualified medical expert like your doctor to find out more about immunisation.

One of the most common questions we get asked is can a child's immune system be overloaded by immunisations and the answer is no.

We know that children, babies come from a sterile environment in the womb and that they are exposed to tens of thousands of bacteria in the first week of life. So the vaccines that we give to children under the age of two are actually a drop in the ocean compared to the environmental challenges that kids are exposed to every day.

The most common scenario we would see where our parent feels hesitant about immunising their child is usually if they have experienced an adverse event or a reaction to a vaccine and that might be as simple as a small local reaction at the site.

Those reactions are quite common with the different vaccines and we do tell parents about those but I think when a parent experiences a reaction from a vaccine first-hand it can be quite confronting and quite distressing.

If parents don't have a close relationship with their health care provider they do often turn to the Internet first and then we do get that Dr.Google phenomenon where they are searching for complex answers to questions and are unsure what information is trustworthy and reputable and which sites to access.

Immunisation effects everybody and it's important for all of us to recognise that it is a community responsibility to immunise our children to keep everybody safe.

Similar to following the road rules, by immunising we can protect not only our children but everybody's children in the community.
