To put it another way, exposure to a virus increases your natural immunity against future viruses.
To give an example of this, 81% of the population already had cross immunity against the WuFlu from having had 1 of 4 other corona viruses. That was why on the infected cruise ship back at the beginning you had some people getting really ill while others got either no symptoms or barely the sniffles.
With virus', what doesn't kill you just makes you stronger. That's my story and I'm stickin' with it.
