Boosters – COVID-19

A booster dose of the COVID-19 vaccine provides added protection for people who have completed their 2-dose primary course more than 3 months ago. Getting a booster dose will provide an extra layer of protection against COVID-19.

Difference between third doses and boosters

Third doses are for severely immunocompromised people as part of a 3-dose primary course. Read more about third doses for severely immunocompromised people.

When you are fully vaccinated

You are still considered “fully vaccinated” if you had 2 doses of a COVID-19 vaccine, even if you had your second dose more than 3 months ago.

Groups at greater risk

The booster is very important for people at greater risk of getting very sick from COVID-19, including:

  • people aged 50 years and older
  • people with underlying medical conditions,
  • people living in aged care and disability accommodation,
  • Aboriginal and Torres Strait Islander people
  • people who may be at greater risk of COVID-19 because of their work.

Booster eligibility

First booster dose

You are eligible for your first booster dose if you are:

  • aged 16 years and older
  • it has been at least 3 months since your second COVID-19 vaccine dose.

Second booster dose

ATAGI has recommended additional booster dose of COVID-19 vaccine for groups at greater risk of severe illness from COVID-19. The intention is to provide these vulnerable groups with additional vaccine protection before winter.

You are eligible for your second booster dose (also known as a "winter dose") if you are:

  • 65 years or older
  • a resident of an aged care or disability care facility
  • severely immunocompromised (as defined by ATAGI)
  • Aboriginal or Torres Strait Islander and aged 50 years and older


  • it has been at least 4 calendar months (17 weeks) since either:
    • your first COVID-19 booster dose
    • a confirmed COVID-19 infection, if the infection occurred since your first COVID-19 booster dose (whichever is more recent).

Read ATAGI’s statement on winter doses.

How to book

If you meet the eligibility criteria, you can book a booster dose if it has been 3 months or longer since your second dose of COVID-19 vaccine. You can book or walk in at any clinic offering COVID-19 vaccines, you do not need to return to where you got your primary course of COVID-19 vaccine.

The date you had your second dose of vaccine is on your COVID-19 digital certificate or immunisation history statement.

Vaccine types for booster doses

The Pfizer (Comirnaty) and Moderna (Spikevax) vaccines are recommended for your booster dose regardless of which vaccine you had for your first 2 doses.

You can also receive the AstraZeneca (Vaxzevria) vaccine if you can’t have the Pfizer or Moderna vaccine for medical reasons. The AstraZeneca vaccine is no longer recommended as a booster dose for people who have had 2 doses of the AstraZeneca vaccine previously, although it can still be used for this purpose if people decline receiving an mRNA vaccine (Pfizer and Moderna vaccines) as a booster dose.

The Novavax (Nuvaxovid) may be used for people aged 18 and over if you can't have the Pfizer or Moderna vaccine for medical reasons.

Safety of COVID-19 booster doses

Common, mild side effects following a booster dose are similar to the side effects following the first 2 doses.

Serious side effects such as myocarditis and pericarditis following a Pfizer or Moderna booster dose are rare.

Vaccination records and certificates

If you get vaccinated at a Queensland Health Vaccination Location, you will get a new vaccination card showing details of your booster dose.

Details of your booster dose will automatically be uploaded to your Immunisation History Statement and your COVID-19 vaccination certificate will be updated to show your last 2 doses.

If you need proof of your full vaccination course (for example when travelling to Queensland) download your Immunisation History Statement from the Australian Immunisation Register (AIR) through the myGov website using your Medicare online account, the Medicare Express Plus app, My Health Record or, if you don't have a Medicare card, by calling 1800 653 809.

Vaccination after having COVID-19

Even if you’ve had COVID-19, you should still get vaccinated. You should wait for 3 months after having had COVID-19 before receiving your next COVID-19 vaccine dose and then get your next scheduled dose as soon as possible after this period. You are far less likely to get severe disease should you get COVID-19 again if you have been vaccinated.

After you have recovered, you can get vaccinated or receive a booster dose. You must not attend a vaccination appointment if you have any COVID-19 symptoms. If you have been vaccinated and have a booster dose, you must wait 3 months before getting your second booster (or fourth dose for groups at greater risk of severe illness from COVID-19, if eligible).
