I know quite a few personally who have taken the shots. Some had nothing at all. Some were sick with flu-like symptoms. I know of 3 that passed one or more weeks after, but no confirmation of it related to shots. A co worker stopped in the other day and said she hasn't been the same since she got hers. She and her husband were reluctant to get it but did anyway because he was told he had to. They regret it now.
