"By injection do you mean the Covid shot?" yes. They lower your over all immunity. No illness ever goes away in your body they're suppressed. When your immunity is weak the body doesn't keep them suppressed which is why we see a large number of childhood illnesses or older illnesses come back.
It was the NIH stated reason why they wouldn't give Informed consent disclosure because it would scare people away from getting the injection.
