To clarify, by "minimal" I mean chances of such serious effects occurring in general.I cannot be dogmatic but just the preponderance of similar things happening lead me to that suspicion. From what I have read I would disagree with your statement that the risks of the vaccine are "minimal". It seems they cause far more problems than they cure. That goes especially for the boosters.
Admittedly there are a lot of discreditable sites on both ends of this issue. For instance I certainly do not believe, like one site claims, that the vaccines will turn people, when the 5G switch is turned on, into robots. But there are also sites that have more credible and detailed information. Like the following. I especially like the downloadable PDF:
The Dangers of Booster Shots and COVID-19 ‘Vaccines’: Boosting Blood Clots and Leaky Vessels
Why "especially the boosters"?
I'm asking because the second shot made me feel bad the next day but I got the flu shot and booster at the same time with no problems. It seems that after 6 months a booster would have no effect other than what had already been experienced (at best).
