Seems to me there is no utility for a vaccine.
Infectious disease experts say that presence of antibodies against SARS-COV-2 are NOT protective against re-infection.
If true, then why would a vaccine protect you?
Secondly, vaccination against SARS itself still has not yielded an effective product. And some vaccines that were tested made patients sicker with SARS re-exposure than unvaccinated.
Just because you want to vaccinate doesn’t mean you are able to do so.
