"…symptoms are not always mild.."
please be specific Mr Reuter whose Board member is also a Pfizzer USA Board member.
CDC numbers to date over 100million Americans tested positive. If it was "not always mild" I would estimate real roughly using my beer can calculator that dividing for days and hospitals I would have to have seen lines of 5000 patients every day every week every month non-stop at every proper hospital since Mar 2020 — unless that did not happen in which case I could categorically state :
"…symptoms are nearly always mild..".
