Shingrix is the new immunization for shingles -- you get two, several weeks apart. I'm sorry that you had an adverse reaction. However, getting shingles is no fun, and a small percentage never get rid of the pain -- the smallpox bug stays in your system for years, and comes out as shingles especially in older people -- my mom was one of those where the pain never went away, and we tried all kinds of meds, etc, etc and never did get rid of the pain. Do some research.
