And with COVID as well 99% who had an infection were not reinfected
I’m not sure where those numbers come from and if they are outdated, but I know a lot of people who got Covid a second time.
None seriously ill b”H, which is why I don’t know if a vaccine is necessary for someone who had Covid (and I certainly don’t think it should be mandated), but those who advise to get vaccinated even for those who once had it have strong basis for that view.
That’s aside from the argument to get vaccinated to lessen the spread.
