Tell healthcare staff before you are vaccinated if you’ve ever had a serious allergic reaction (anaphylaxis).
You should not have the vaccine if you’ve ever had a serious allergic reaction to:
- a previous vaccine
- a previous dose of the same COVID-19 vaccine
- some medicines, household products or cosmetics
Serious allergic reactions are rare. If you do have a reaction to the vaccine, it usually happens in minutes. Staff giving the vaccine are trained to deal with allergic reactions and treat them immediately.
You can report any suspected side effect using the Coronavirus Yellow Card safety scheme.
