After your COVID-19 vaccination
Find out what to do after you are vaccinated for COVID-19, including how to get your vaccination certificate, what you need to do to stay safe and what to do if you have side effects.
It takes time to build immunity
It takes time for your body to build up an immune response after you get your vaccination.
Most people need 2 doses to get strong protection against the virus that causes COVID-19.
The first dose gives you partial protection as soon as 12 days afterwards. The second dose encourages your body to create stronger protection (immunity).
It takes 7 to 14 days after your second dose before you are fully protected.
Some people may need a third dose if they are severely immunocompromised to give them full protection.
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.
ATAGI is assessing the evidence for booster doses and will issue more detailed advice by the end of October 2021.
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.

Hygiene and masks
To protect others and yourself continue to follow all local restrictions, including wearing a mask where required.
You should also continue to practice good hygiene and follow all precautions to help prevent the spread of the virus.
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.
You can check any symptoms you are experiencing through healthdirect's symptom checker.
You can also call the national coronavirus and COVID-19 vaccine helpline on 1800 020 080 any time.

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.
At this time, domestic travel restrictions still apply to you after vaccination.
