An interesting article that scurrilously impugns the motives of the drug industry, regulatory agencies,
and collaborating "news" media ---
"How Drug Industry Is Countering Diminishing Vaccine Uptake"
--- probably should be dismissed out of hand since the author was demoted by google-fact-checkers.
One might conjecture, though, based on its references that exposure to known attenuated corona cold
viruses could induce anti-Covid immunity fairly safely, quickly and inexpensively -
but, that's obviously wrong-think, as our regulatory agencies funding preferences prove.
