Like any vaccine, COVID-19 vaccines can cause side effects, although many people do not experience them.
The vast majority of side-effects are mild and short-lived. They can include pain where you received the injection, tiredness, fever, chills, nausea or a headache. Severe events after vaccination are extremely rare.
For COVID-19 vaccines that require two injections, side effects from the second shot may be greater than after the first. This shows that your body is building protection and should go away within a few days. If side effects worsen or don’t go away after a few days, contact your healthcare provider.
COVID-19 vaccines are proven to significantly reduce the risk of severe illness and death from the virus.
