The problem is, all these mandates were instituted long after the Provincetown study, which made it clear that Delta was also exhibiting significant vaccine escape and herd immunity was impossible. Any notions of "stop the pandemic" were absurd past that point. A lot was missing from the original trials as well. No study of impact on transmission, no routine testing to detect asymptomatic cases.
