short version is ... spent 3 workdays on a trip away from home in a confined area with a colleague who was cv vaxed. Not only is the typical facecovering ineffective, it's also a hindrance to safety in this application. The second night I awoke with a small campfire in my chest. not a heart issue. took my vit c, and sniffed my peppermint oil a few times. That initially made it worse, but the other cause was treated and I soon returned to sleep.
The next night ... at home ... I was up for almost 3 hours trying to get the thing beat back.
This was the first person I had encountered with declared CV Vax and no one with whom I have shared this confined space has opted to keep their status private.
So .... I can't be 100% sure, but my level of certainty is at least as high as anything the CDC has pushed ... or the declared effectivity of Pfizer's potion.
I won't berate anyone for taking the cv vax, but do not be deceived, this potion is not the answer to this pestilence. They're already giving boosters in Israel and soon will be here as well. no boosters is one of the big 3 anticipated advantages of the mRNA type vaccine. Seems it's petering out before a standard Modified Live Virus type.
