It takes time to build immunity
It takes time for your body to build up an immune response after you get your vaccination.
The ATAGI recommended doses and vaccines outlines which vaccines and doses are recommended for each age and population group.
The first dose gives you partial protection as soon as 12 days afterwards. The second dose encourages your body to create stronger protection (immunity). A third dose is required for severely immunocompromised people.
A booster dose will make sure the protection from your first doses is even stronger and longer lasting, and should help prevent spread of the virus.
It takes 7 to 14 days after a dose before you are fully protected.
Find out more about booster doses and third doses for people with severe immunocompromise.
How long protection lasts
We do not yet know how long the protection from COVID-19 vaccines will last. Ongoing research around the world is evaluating:
- how long protection lasts
- whether you will need booster doses, such as an annual booster.
Right now you can book your booster dose if it has been 6 months or longer since your last dose of your COVID-19 vaccine.
Learn more about booster doses.
Get a COVID-19 digital certificate
Once you are fully vaccinated, you can get a vaccination certificate. It can take about 2 weeks after your second dose to become available.

Serious or allergic reactions to vaccines are very rare. They usually occur within 15 minutes of receiving a vaccine.
You will be monitored for at least 15 minutes after your vaccination. The person who gives you the vaccine has been trained to respond to immediate reactions.
If you have side effects of vaccination
Most potential side effects are mild and go away in a few days. Very rarely, side effects might be more serious.

Report a suspected reaction or side effect
Reporting suspected side effects and reactions helps us monitor vaccine safety. Every report is valuable and helps ensure vaccination is safe.
If you or a health professional thinks you have experienced a reaction to or side effect of vaccination, please report it.
You can ask a health professional to report to the Therapeutic Goods Administration (TGA) on your behalf.
Or you can report side effects yourself:
- to your state or territory health department
- to the NPS MedicineWise Adverse Medicine Events Line on 1300 134 237
- via the TGA's online reporting form.
If you have experienced a rare side effect you may be eligible for compensation under our COVID-19 vaccine injury compensation scheme.
