It’s a common mistake to believe that our personal experiences are typical. It even has a name, the Availability Heuristic. Some use the term anecdote.
But when making decisions about things like whether to vaccinate or not vaccinate, it’s important to look at probabilities. And to do that we have to look at what happens to large groups of people. Thankfully, this has been done. Various studies have been conducted which looked at large groups of people, literally millions in some cases and their conclusions have remained consistent.
They are that the vaccine has some risks, but they generally are mild. But more importantly, the risks of the vaccine are lower than the risks from getting Covid.
That doesn’t mean that everyone who gets vaccinated won’t have a side effect, or that everyone who isn’t vaccinated will suffer be injured by Covid, but it does mean that, on average, you are far better to be vaccinated than unvaccinated.
