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 4 months ago.
Third doses are for severely immunocompromised people as part of a 3-dose primary course. It is recommended to have the third dose 2-6 months after the second dose. Read more about third doses for severely immunocompromised people.
Getting a booster dose will provide an extra layer of protection against COVID-19.
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 4 months ago.
- Over 18 years of age
- 4+ months since second COVID-19 vaccine dose.
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.
How to book
You can book a booster dose if it has been 4 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
- had 2 doses of the AstraZeneca vaccine previously.
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, or My Health Record; or by calling 1800 653 809 if you don’t have a Medicare card.
Vaccination after having COVID-19
Even if you’ve had COVID-19, you should still get vaccinated. 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 your booster or third dose. You must not attend a vaccination appointment if you have any COVID-19 symptoms.
