Coronavirus vaccines are the world's escape route out of a pandemic.

Vaccines from Moderna, Pfizer-BioNTech, AstraZeneca-Oxford University, and Johnson & Johnson have been approved in the UK. In the US, all of them have been authorized except AstraZeneca's.

Each is given as a shot in the muscle of the upper arm.

You might not get a choice about which COVID-19 vaccine you get, but all four offer some protection against severe illness, so the advice is to take one if you are offered it.

For the two-dose vaccines, you should have two shots of the same one, where possible.

Speak with your doctor if you are pregnant, breastfeeding, have a specific medical condition, or take medicines -especially if they thin your blood or affect your immune system. Experts have said the COVID-19 vaccines won't make you infertile. Side effects may start within a day or two and should go away within a few days.

We've made a table that gives you the key information for each shot, whether you've booked an appointment or not. Scroll down to view it.
