There's quite a bit about them in the forum. Especially in the Coronavirus thread. But it's over 1,000 pages long; so it'd be more helpful to put the words Pfizer and Moderna or whatever other description you like, in the search engine and many pages should pop up. You can find the search at the top of the page.Apologies in advance if this has already been discussed: Do we have any comments on the safety rate of the various types of vaccines somewhere here? How about the Sinopharm: SARS Cov 2 (verocell) inactivated in comparison to the Pfizer and Moderna mRNA types? That's what they are rolling out at my workplace now....
Also, there's this good thread by Gaby, Health Protocol for Mandatory Coronavirus Vaccination.
