Vaccines are not magic. Every treatment has potential downsides. That's why they need approval to weight the potential benefit/harm trade-off.

From everything I've heard, these particular vaccines are pretty close, though.

90-95% reduction of risk.

Maybe even greater reduction of serious disease?

Most common side effect people seem to talk about is something like fatigue and fever for a day or two after a shot?

That's a pretty good tradeoff. Especially when you consider that getting large populations vaccinated pretty much ends the pandemic.
