When you know someone who is suffering from an incurable vaccination injury, the favorable odds of you not getting a vaccination side effect doesn't seem comforting. It's like playing Russian Roulette with a 500,000 chamber revolver. What are the odds that your spin lands on a loaded chamber? Well, there are many medical professionals making the informed decision of not taking the Covid shot even given those favorable odds you won't land on a loaded chamber.
(I feel for people who are strong-armed into taking the Covid shot by their governments or employers. It's tough to choose between being able to pay your mortgage or rent and your personal freedoms involving "your body your choice.")
Vaccine injuries are documented but not well known nor widely mentioned. They should be. The CDC has a webpage of known vaccine injuries. You won't see an entry for Covid and its strains. At least not yet.
For FYI anyway ...
