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.
If the initial test results were misrepresented, it's fraud. No protection from liability and the government's contract would be junk. Unfortunately, the contract was signed by the same entity that brought us the problem, imo.
