Per caller: " patient took the booster vaccine the other day, and have 12 of the side effects listed on the card. She took both doses the first time and had no reaction. She poke to her doctor and she suggested she take Tylenol for the fever". Side effects after your second shot may be more intense than the ones you experienced after your first shot. These side effects were normal signs that your body was building protection and should go away within a few days.
