I think this is definitely part of the explanation.
> A lot of immunocompromised people in SA (AIDS)
Wouldn't this mean more deaths or am I missing something? Are COVID deaths in AIDS patients attributed to AIDS not COVID?
> UK has most of it immunity from vaccination which was mainly targeting AC2 receptor. It's possible that natural immunity or Sinovac (attenuated virus) has better protection than mRNA vaccines - not confirmed.
Okay, so should we perhaps not be pushing vaccination on healthy individuals? I had a COVID infection early on in the pandemic and I've interacted with infected people since and not caught it. My sister who's younger than me (in her 20s), but was vaccinated before being infected has tested positive for it 5 times. Perhaps just a coincidence but odd that she's so much more susceptible to it.
> SA is doing fewer tests.
Sure, but deaths are much lower too.
