Firstly, I'm not an anti-vaxxer - I've had two AstraZeneca shots and a Pfizer booster - but had I seen this video before being offered the booster, I might've decided against it given that I experienced serious adverse side-effects which left me feeling poisoned and bed-ridden for almost 24 hours. I did, at the time, have my reservations knowing Pfizer's track record, but said "fuck it" and went for it anyway. In retrospect, I'm still unsure if it was the right thing to do.
I also know of someone who was inoculated with the Pfizer booster one day and died the next of a serious heart-attack.
The bottom line is it's difficult to know what's real and unreal in the Disinformation Age, but this video from the Canadian Covid Care Alliance is, I think, worth exploring and raises some serious questions.
