Question & Answer #7

How long will the COVID-19 vaccine last once I have had 2 doses?

Answer:

It is not yet known how long the protection of the COVID-19 vaccine will last. We will know more through ongoing research. Clinical trials are currently happening to find out if we will need booster doses on an annual or longer basis.

What we do know is that evidence shows the Pfizer (Comirnaty) and the AstraZeneca (Vaxzevria) COVID-19 vaccines prevent severe disease, people going to hospital and dying. The aim of Australia’s COVID-19 vaccination program is to reduce COVID-19 related harm. Vaccines do this by preventing serious illness and death, and, as much as possible, transmission of the virus that causes disease.
