Coronavirus vaccines are the world’s escape route out of a pandemic that has closed schools, grounded flights, and left millions dead.

Several vaccines have been approved in the West, most notably from Moderna, Pfizer-BioNTech, and AstraZeneca-Oxford. Each is given as a shot in the muscle of the upper arm and requires two doses.

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

We’ve made a table that gives you the key information for each shot, whether you’ve booked an appointment or not.

Side effects could start within a day or two and should go away within a few days.
