You have my sympathies if indeed you did have a severe adverse reaction from a Covid vaccine. I say "if" because honestly, anyone can say anything on the Internet. That doesn't make it true.
But let's assume it is: by itself, it's basically irrelevant. What you've presented, if 100% true, is an anecdote. These situations need to be looked at in aggregate. To start with:
- How common is it? Is it 1 in 10,000 or 1 in a billion? What level is acceptable?
- Is the likelihood of adverse effects related to Covid risk factors? Example: this submission is about the prospect of an elevated risk of myocarditis for young recipients of the Moderna vaccine. Well, that's also an issue for people who get Covid. So the vaccine's adverse reaction may go hand in hand with an elevated risk of severe Covid outcomes due to the same underlying risk factors;
- How does the likelihood of severe vaccine reactions compare to the decreased chance of severe Covid outcomes (eg being on a ventilator, long Covid, death)?
- Factored into the above, what about the improvement in outcomes for the population as a whole from having a sufficiently large number of vaccinated people (ie herd immunity)? This also includes people who genuinely cannot get the vaccine.
- Not getting the vaccine clearly increases severe outcomes from getting Covid. Based on the data, this is undeniable (eg 98-99% of Covid deaths are now among the unvaccinated). Being unvaccinated means you increase the chance of needing expensive medical treatment. It may also mean using up a bed that's needed for something completely unrelated to Covid (eg a heart attack).
On the last point, I guarantee you you'll be dealing with medical professionals who essentially have PTSD because they have to come to terms with the fact that they've chosen who gets to live and who gets to die because there simply aren't enough beds.
But sure, never mind that. There's a one in a million chance of an adverse reaction so screw em, basically.
