A link to the study. And that’s an...interesting read.
Do you have a synopsis for folks like me who aren’t medically adept?
\ Excepting from the title: "imprinted by infection or vaccination."
So "safe and effective" as was the marketing and politics of the "event" was neither fully safe nor fully effective.
From the Discussion section: "Clinical data suggest that any prior exposure to SARS-CoV-2, whether through infection or vaccination, significantly reduces the severity of subsequent infections."
Seems as if natural immunity from a healthy immune system is far safer and more effective. And the many boosters show themselves a marketing gimmick.
Even though the study was a very small sample, the rigor was clear.
The hot link is very much appreciated. And the actual, documented mortality rate worldwide over the entire course of the 'pandemic" stands at about 0.08 percent. Seems the pandemic was most visible in the media hype. And the politics.
