Chickenpox is a very contagious infection caused by the varicella zoster virus. Most people with chickenpox have mild symptoms and recover quickly. In rare cases, the virus can cause serious complications such as pneumonia or meningitis.
Vaccination is the best protection against chickenpox. If you're eligible, you can get chickenpox vaccines for free under the National Immunisation Program (NIP). See more information about when to get vaccinated.
Since the chickenpox vaccine was added to the NIP, there have been far fewer hospitalisations and deaths due to chickenpox in Australia. Immunisation prevents most cases of chickenpox and reduces the chance of serious illness and complications.
