19 out of 16,000 is 0.1%. so 99.9% don’t get it twice. As expected. Just like SARS-1-CoV.
There is almost zero chance of getting it twice.
We will never get decent test data for infections and re-infections. The reason for this is the testing all involves turning people loose to walk around in society and having no idea if they ever encounter the virus to become infected.
If someone has been infected before, chances are they’re paranoid about it and will be the ultimate in social distancing and mask-wearing. Of course they don’t get re-infected. They make damn sure they’re never around anything that might infect them.
A proper test would have the test subject inhale virus and see if this supposed acquired immunity can stop it. That test will never be done, it will never be approved, and probably no test subject would be willing to do it. The exact same reality is true of vax versus non vax. You have no idea if the test subject ever encounters the virus.
“There is almost zero chance of getting it twice”
BRING ON THE HERD!
The ONLY way to be sure.
If you die, you die. The rest of us will be immune. The virus will also be DEAD!
Costs NOTHING! Economy can roar back. Life can return to normal, the OLD normal.
