Extra Chickenpox Vaccination

An extra chickenpox (varicella) vaccine dose can give your child stronger and long-lasting protection. However, it is not part of the free government schedule and will involve a private cost. It is an individual choice, and your GP can help you weigh up the benefits and downsides for your family.

What is the standard chickenpox vaccine?

  • In Australia, children are routinely given one dose of chickenpox vaccine at 18 months, as part of the combination MMRV (measles, mumps, rubella, varicella) vaccine
  • This funded dose provides good protection against severe disease for most healthy children

Why consider an extra dose?

  • One dose prevents severe chickenpox in around 65-82% of cases, and a second dose increases protection to about 95% effectiveness

  • A second dose can be given at least one month after the 18-month dose
  • A second dose can help reduce your child’s risk of catching and spreading it, especially in childcare and school settings where we aim to give the vaccine within 3 days of exposure

Reasons you may choose not to

  • Cost – $75. The extra dose is not funded on the National Immunisation Program
  • Even with a single dose, most children are well protected, and, if they do get chickenpox, it is usually milder and shorter than in unvaccinated children
  • All vaccinations can cause side effects such as a sore arm, mild fever, or a small rash, a very rarely, more serious reactions. Your GP can discuss these with you further.

How to decide and where to get more information

  • Speak with your GP about your child’s medical history, family circumstances, childcare/school exposure, and the costs, so you can decide whether an extra dose is right for you
