AAQ -“Just speculating what could be the difference between re-infection and infection after vaccine:”
The key word is “Speculating”.
That’s the problem in the US.
They keep Speculating.
The Anti-Vaxxers keep Speculating that they are immune, because they had Covid 19 Once.
And the Genocidal Government doesn’t recommend a third shot after the First two.
I have No problem with all those that rely on their own speculations, but not with Lab testing.
My Beef is with – when s/o gets Ill with Covid 19 – they should be allowed to take anything that they think could work against it!
