Saying "but vaccines can kill you!" is a stupid reason not to get them. Anything can kill you. People are killed constantly by things that sound like they shouldn't kill them. You could go out for a drive and get hit by a seeding car and die, are you no longer going to drive? You could go for a walk and a tree could fall on your head, are you never going to go outside again? You could be sitting inside and your house could have a gas leak and explode. Are you going to buy an underground reinforced shelter, because even then, that can kill you as well. Because that is how life works.
