- There are several different types of COVID-19 vaccine. Most of them work against both the beta (B.1.351) and delta (B.1.617.2) variants.
- They train your immune system to recognise coronavirus and prevent it from making you severely ill.
- They do this by introducing inactive bits of the coronavirus into the body so that your immune system learns to recognise the virus.
These bits of coronavirus are not live and cannot make you sick.
If you then catch coronavirus from someone with COVID-19, your immune system recognises it quickly and prevents it from making you very ill.
COVID-19 vaccines will protect you from becoming severely ill or dying from COVID-19. They will help to keep you healthy so you can be there again for your family and friends.
