They now have a new, supposedly more effective, Shingles vaccine. It requires two injections instead of just one. I haven't had one yet, but, intend to do so on my next Doctors visit.
Is anyone else as old as me and remember going to public places and getting Polio Vaccine shots. I was young, but, it seems like that required more then one. I'm thinking three over a period of time, but, I really don't remember clearly. At the time, anyone coming at me with what seemed like a 6 foot long needle was one to many. Now needles are so small and sharp that you really don't even feel them, back then the technology was a lot more primitive and there were many dull ones (I think they reused them a lot too.) I even had one break off in my arm when I was about 10 years old. That wasn't pleasant.
