Coronavirus vaccines are the world's escape route out of a pandemic that has shut down schools, grounded flights, and left millions dead. Vaccines from Moderna, Pfizer-BioNTech, AstraZeneca-Oxford University, and Johnson & Johnson have been approved in the West. In the US, all of them have been authorized except AstraZeneca's — in the UK, all of them except Johnson & Johnson's are authorized. 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.
