Someone I know has first hand knowledge, documentation, that the covid vaccine has caused a large increase in cancer patients being treated at our hospital.
I just got an advertising mailer from that same hospital to go get a covid booster. To be fair to the local hospital, that mailer came out of corporate headquarters in another state.
What study would you like to wait for?
Increase in cancer patients could be neglect of following up on symptoms during lock-downs... also probably what you are thinking, decreased immunity due to vaccine side effect... I’ve seen that postulated... especially in UK news reports...
The one that proves clinically that this syndrome is caused by mRNA vaccine... if we allow ourselves we can go to a place where we literally blame every death/illness on covid or the vaccine... I’m just cautioning about that... I’m not saying there aren’t problems with the vaccine.
