Immunisation is one of the most effective strategies to protect children and adults against certain diseases with various immunisation programs available in South Australia. Immunisation not only protects individuals, but also others in our community by increasing the level of immunity and minimising the spread of disease. When a large percentage of people in the population are immunised against a specific disease, it becomes harder for that disease to spread. Immunisation uses the body’s natural defence mechanism – the immune response – to build resistance to infectious diseases. The benefits of immunisation far outweigh the risks from the diseases they seek to prevent.
Young children, particularly babies, do not have the well-developed immune system that older children and adults have. Most vaccinations need to be given more than once to build long lasting protection – this is why it is important for children to complete the full recommended schedule of vaccinations at the recommended times. Sometimes it is possible to ‘catch up’ if the vaccinations are not given on time. However, some immunisations like the rotavirus vaccine cannot be given later than the recommended time. Not getting the full course of vaccinations can leave a child unprotected and still at risk of getting the disease.
There are many vaccines that protect against infectious diseases such as:
In the pre-immunisation era these diseases were common and caused significant disability and death. With the advent of vaccination the occurrence of these illnesses are now either diminishing or are rare in countries that have strong immunisation programs, such as Australia. However is still vitally important for children and adults to be immunised. Vaccination ensures those diseases are not reintroduced or that serious outbreaks of those diseases do not occur.
Immunisation also plays a role in protecting against certain non-infectious diseases. Research shows that certain viruses are associated with some types of cancers. Examples include the hepatitis B virus and its association with liver cancer, and the human papillomavirus (HPV) and its association with some cancers in the genital area. Vaccines for both hepatitis B virus and HPV are available.
Your doctor or immunisation provider should discuss the following before you consent to being vaccinated:
- effects of the disease
- possible side effects of vaccination
- what to do to reduce the side effects.
They will also ask you if you are unwell, pregnant, have any allergies or have previously had any reactions following any other vaccines as in some instances immunisation may need to be deferred or further medical assistance may be needed. Remember, you or your health professional can report vaccine reactions.
Although vaccination is safe for the vast majority of people there are some people who, for various reasons, may not be able to be vaccinated or who may not be able to receive certain vaccines, for example allergies or current health status. It is important to discuss risks or side effects of vaccination with a health care professional before being immunised
Talk to your doctor before being vaccinated if you:
- are pregnant, breastfeeding or planning a pregnancy
- have previously had a serious adverse event following immunisation, or
- have impaired immunity due to disease or treatment
- identify as Aboriginal or Torres Strait Islander.
Other vaccines may be recommended, but not free to all groups include vaccines:
