Immunisation for children: Sorting the facts from the fiction

Choosing what to put in your child’s lunchbox can be a hard decision. Add to this the question of whether or not to immunize them and it becomes even more difficult.

Immunization is one of those topics that you will find both sides passionately arguing for their opinion on, with many different reasons behind their choice. This blog post will hopefully clarify the facts and fiction about immunization for children and give you all the information you need to make an informed decision as a parent, guardian, or caregiver.

Despite the increase in education around children’s vaccinations, there are STILL a lot of misconceptions out there that can be confusing. And never has there been a better time to remind us all how immunization really works. So to set the record straight, here are seven true immunization facts all parents need to know.

1. Immunisation has been around for centuries

The first vaccine was developed in 1797 for smallpox – a disease that no longer exists. Over the centuries, many more vaccines have been introduced for diseases such as cholera, rabies, influenza, chickenpox, tetanus, and whooping cough; which has helped to significantly reduce the number of cases occurring in communities worldwide.

2. Immunisation saves lives

Vaccines are a safe and effective way of protecting babies and young children from serious childhood illnesses such as measles and whooping cough, which in severe cases can result in death.

3. Vaccines are safe

In Australia, all vaccines go through a strict testing process with the Therapeutic Goods Administration (TGA) to ensure their safety and effectiveness. They are also then continually monitored and evaluated for ongoing safety.

4. Side effects are minimal

Some children (but not all) may experience minor side effects following immunization such as a mild fever, or pain or swelling where the injection went in.

Most side effects don’t last very long and the child makes a full recovery quickly. Only in rare cases will a child have a more serious reaction, such as an allergic reaction (in this unlikely event, immediate medical attention should be sought). 

5. They strengthen the immune system

Vaccines use the body’s natural defenses to help build a strong immune system. When a child is immunized, their body will be able to quickly recognise and respond to viruses because they have already been exposed to them in small weakened doses via vaccines.

The body can fight better when it knows what it’s up against. The only other way for children to become immune to a disease such as measles is to contract it in its full form, which can be dangerous and even life-threatening.

6. It is best to give vaccines on time

We get it, you’ve got your hands full with a newborn and think you’ll just put off their vaccines for a while. Or perhaps you’ve done the first couple and now they’re older, you don’t think they need any more. Wrong. For the best protection, all children need to receive their vaccinations on time, otherwise, they remain at risk of infection.

However, it is important to note that parents of children with special circumstances – such as some disabilities, allergies, or genetic illnesses – can arrange a delayed immunization schedule under the careful guidance of their child’s doctor. 

7. Australia still needs higher immunization numbers

Although 93.5 percent of all five-year-old children are vaccinated, in some areas the numbers are much lower. Some people can’t be vaccinated due to their age or other medical conditions.

In places with high levels of immunization, any infection introduced into the community cannot spread easily from person to person, so these unvaccinated people get some protection. This is called ‘herd’ or community immunity. If not many people are vaccinated, the disease can spread more easily.


Immunization for children: Sorting the facts from the fiction Immunization has been around for centuries. Vaccines are a safe and effective way of protecting babies and young children against serious childhood illnesses such as measles, which in severe cases can result in death.

Although 93.54 percent of five-year-old children are vaccinated, there’s still room to improve immunization numbers throughout Australia.
