I'd put it differently. We know that the vaccine absolutely saved millions of lives. Covid directly killed millions of people plus the millions more who have life-long complications from it. The vaccine is like any substance that goes into our bodies, it might have complex interactions with the functioning of the body, just as is true for the foods we eat, the things we encounter in our environment, even aspirin was recently reconsidered as a general thing to take daily. The vaccine has been extensively tested and now we have real world testing with billions of doses given that it is extremely safe. It's hard for people to talk about any potential concerns because of the huge number of people fixated on the fact that it could have other effects (like every single medicine in the world) who constantly make bad faith arguments (you have some sickness and got the vaccine and thus they claim the "obvious" connection). People had difficult to diagnose things like chronic fatigue syndrome before there was ever a covid vaccine and we don't understand those either.
