Some side effects from COVID-19 vaccination, such as fever, might be similar to symptoms of COVID-19 itself. However, neither of the vaccines contain any live SARS-CoV-2 virus and can’t cause COVID-19. You may not need to get a COVID-19 test or isolate: if you develop general symptoms such as fever, headache or tiredness in the first 2 days after vaccination, and if you are sure that you don’t have any respiratory symptoms (such as runny nose, cough, sore throat, loss of smell or loss of taste) However, you should check the current guidelines in your state or territory for the most up-to-date information. This advice may change in the event of a COVID-19 outbreak in your local area. You may still need to get a COVID-19 test if you meet other criteria — for example, if you are a close contact of a known COVID-19 case.
