The shingrix vaccine is a dead virus vaccine. Both my PCP and Dr Villa Forte recommended I get it. After the first dose, I had a sore shoulder at the injection site (as with a tetanus shot) for about two days. I had the second dose two months later. After this dose, I had flu-like symptoms (body aches and low grade fever) the day after the injection. I also had a sore shoulder for five days. I was back to normal five days after shot #2.
