This thread has gotten a little off track, but I hope Charlotte won't mind me adding my opinion about the newer, two-part shingles vaccine. I don't want to talk anyone else out of shingles vaccination. Just want to offer food for thought.
I decided I wanted the vaccine after declining it for many years, but I didn't just charge ahead. I found a medically-reviewed article in US News and World Report from last November titled, "Why You Should Get the Shingles Vaccine Soon". Dr. Ardeshir Hashmi, a geriatrician and endowed chair at Cleveland Clinic is quoted in the article. He says that for people who have any sort of autoimmune disease, "the shingles vaccine, specifically, is not for them." The entire article can be found here ~

I didn't stop researching there. I also learned that Shingrix is made with Chinese hamster ovary cells, the same as Rituxan, Humira, and some other drugs. Since I had such an abysmal reaction to Rituxan, I'll have to take my chances with shingles itself.
