wait till they admit covid was a hoax and what changed was the dr/hospital protocols in treating an upper-respiratory flu...this same flu was dominate in 2017 to 2018 and the protocols used then were not the same in 2020...check i will wait...hell they were telling people to go home and come back within 14 days if you start feeling worse without a prescription and we all know how docs love their 'script pad (i do know their are good docs out there that "do no harm")
