Not trying to scare anyone away from vaccine, just found this interesting. I take it with a grain of salt(for flavor) and the fact that we don't know how many participants react this way. News stories have a way of finding one or two people that things are the worst for and then making the story seem like its happening to everyone, when we have no idea...that's mainstream media though.
