> A female close to me experienced side effects from shedding of the vaccine

There are always risks with vaccines, given you are trying to introduce an immune response to a contagion and it's no secret that the immune system can get it wrong (e.g. overreacting, attacking own tissue). It's about balancing the benefits of the vaccine with the risks. You can get the same consequences from having the disease itself, as well as the risks the disease will kill you.

The COVID shot was deployed in a little amount of time, so it's understandable that there are more notable cases of side effects, because it was deployed over months, not decades as is the case with other vaccines.

Think of it from this perspective: you made a claim but you don't have data to support it. It's easy for individuals to be prone to false conclusions because we often conflate weak correlations as causation, when often times, randomness is a better explanation, or "not sure if causation".
