COVID-19 booster vaccine advice

Learn about booster doses for COVID-19 vaccines, who they are for, when you need one and how to get it.

To receive the best protection against serious illness or death from COVID-19, you should get all recommended doses for your age or individual health needs. COVID-19 vaccines are free for everyone.

Depending on your age and risk factors, you may have been eligible for one or two COVID-19 booster doses in the last 12 months.

If you already received your recommended dose/s in the last year, you do not need any other doses at the moment and should wait until new advice is provided. If you haven’t had your recommended dose/s in the last year, or become eligible for an additional dose in the next few months, you should get the doses recommended for you as soon as you can.

Updated recommendations are expected soon.

Booster doses

A booster dose is recommended for all adults:

  • aged 65 years and over
  • aged 18 to 64 who have medical comorbidities that increase their risk of severe COVID-19
  • aged 18 to 64 who have a disability with significant or complex health needs

You can also consider a COVID-19 booster dose for yourself or someone you care for if you have spoken with your healthcare provider and are:

  • an adult aged 18 to 64 years without risk factors for severe COVID-19
  • a child aged 5 to 17 years who has medical comorbidities that increase their risk of severe COVID-19 illness
  • a child aged 5 to 17 years who has a disability with significant or complex health needs

A second COVID-19 booster dose is recommended for all adults aged 75 years and over

All adults aged 65 to 74 years, and adults aged 18 to 64 years with severe immunocompromise can get a  second booster dose after discussion with their healthcare provider.

All boosters are available six months after the last dose received.  If you’ve already had your recommended booster/s, you don’t need to get another dose, even if it has been six months since you had one. 

Booster doses are not recommended at this time for children and adolescents under 18 years of age who do not have any risk factors for severe COVID-19.

All vaccines approved for use in Australia continue to give strong protection against serious illness from COVID-19.

The date you had your last COVID-19 vaccine is on your COVID-19 digital certificate.
