I think we will know better this fall/winter when we have a new cycle of flu/influenza/coronavirus make the rounds. We will see if there is truth that the boosters are further weakening the immune system to the point that people will have a hard time fighting off wild viruses. I have a BIL close to death with a fast moving, aggressive cancer and am hearing stories of a huge number of cancers happening in my city. It is hard though to correlate that with the vaccine isn't it?
