How the vaccines are now doing stopping you getting Covid. ChAdOx1-S is AstraZeneca. BNT162b2 is Pfizer. mRNA1273 is Moderna. In a nutshell, they're not really stopping infection at all, after 20 weeks, even with 3 doses. Effectiveness against dying from Covid drops to about 60%, at 25 weeks, if you haven't had a 3rd shot. (Get your 3rd shot. Wear a mask, avoid crowds, get fresh air into your buildings etc.) The vaccines are struggling because we're not doing anything else, so they're having to try to do the lot.
