Sorry, but that's just not how it works, by now there's plenty of evidence that initial viral load exposure plays a major role in the later disease progression, which is not something unique to SARS-CoV-2.

As such it's very much part of the whole spectrum of outcomes from "Asymptomatic to mild symptoms" to "Ending up on a respirator and dying".

These are basics, and I'm not gonna discuss them with some random stranger who, once again, tries to politicize rather common sense, and established, medical practices.

Yes, the top of the bell curve is sadly a very crowded place.
