You can definitely get it more than once. My wife had it 3 times in spite of the jabs. You can test positive up to a year after getting it. And yes there is a lot of bogus information about it all. Insurance actuarial tables are most interesting. Huge increase in deaths from all causes. Massive class actions on the way if whistle blower claims of fraudulent research are corroborated. No emergency liability protection if they lied.
