How many serious adverse effects are allowed during the clinical trial of vaccines before the trial is closed and deemed dangerous? I’ve tried to look this up. To see if there are guidelines, but I can’t find it. Is there a percentage?

Depends on the trial and the input from the ethics boards.
For the SARs2 vaccines its listed in the early phase clinical trial papers.
Its not a percentage as thats far too simplistic to be useful (it needs to be risk:benefit and so on).
