COVID-19 third dose vaccinations
A COVID-19 third dose helps prevent waning immunity (loss of protection) against COVID-19. A third dose is important to give you maximum protection against COVID-19 and to help reduce the spread of the virus.
COVID-19 third doses are now available to anyone aged 18 and over who had their second dose of a COVID19 vaccine three or more months ago.
If are eligible for your third dose and have had COVID-19 recently, you should get your third dose as soon as your symptoms subside.
Frequently asked questions
Most people will receive the Pfizer or Moderna vaccine as their third dose. You can get either vaccine as a third dose regardless of which COVID-19 vaccine you received for your first two doses. Some people may receive the AstraZeneca vaccine as their third dose if they cannot have an mRNA vaccine, such as Pfizer or Moderna, for medical reasons.
If you are not sure which third dose vaccine you should have, speak with your doctor.
You might have side effects. Side effects are normal, usually mild, and go after a day or two. You might not have any side effects at all, but if you do, they include:
- pain where you had the needle
- muscle aches
- fever or chills
- joint pain.
Serious side effects are very rare. Contact your doctor if you are worried, or if any side effects have not gone away after a few days. Call 000 if you have a serious reaction such as trouble breathing, chest pain, a fast heartbeat, a seizure (fit) or if you collapse.
Even after a third dose, you still need to be COVIDSafe.
To stay COVIDSafe:
- wash your hands with soap and water often, or use hand sanitiser when you cannot wash your hands
- keep 1.5 metres distance from other people (physically distance)
- wear a face mask inside or when you cannot physically distance
- cough and sneeze into a tissue or your elbow.
Get tested for COVID-19 if you:
- feel even a little unwell
- have been in close contact with someone who might have COVID-19.
Do not go to a vaccine appointment if you feel unwell or think you may have COVID-19.
