All the people talking about how the vaccine has been fine remind me of the people who brag that their new vehicle has had very few problems in the first week.
I honestly don't think there are going to be any big problems with these mRNA vaccines. Still, being that this is pretty new stuff, it can't be completely ruled out, and if there are problems they will probably arise later on. If nothing negative has happened couple years, I'll call it a success.
