As vaccine experts, we hear these concerns all the time, and it’s normal to have questions about a vaccine.
The good news is that scientists have already been testing COVID-19 vaccines for months. For starters, serious side-effects are very, very rare. And, together with what we know about previous vaccines, if side-effects are going to occur, they usually happen within a few months after getting a vaccine. This is why international medical regulators, including Australia’s Therapeutic Goods Administration (TGA), require the first few months of safety data before approving new vaccines. This, plus information coming from vaccine recipients in the northern hemisphere, gives us confidence that COVID-19 vaccines are safe.
In fact, most side-effects occur within the first one or two days. And most of these are minor, such as pain at the injection site, fatigue or fever — which are signs your immune system is building a response against the thing you’ve been vaccinated against.
