Another thing that is alternating between “itching my ass” and putting me into a “burning rage worthy of a gamma ray burst” is people using the term “natural immunity” to describe the state of being after having COVID.

That is not natural immunity. Natural immunity is when you were born with a mutation or a genetic trait that makes it so the virus cannot infect you.

If you get the disease, you have temporary acquired immunity, just like a vaccine, it’s just you acquired it from the virus itself.
