I would encourage ever one to get them Who are 50+
You get the first one then 2 months later you get the booster. If you know of anyone who has gotten them before it is a very painful experience.
If you have never had chicken pox then You don't need to worry about the shot. The shingles lies dormant and can reappear when under stress.
I got mine while taking the flu shot. I will have the protection from shingles for the rest of my life no need to have boosters. your insurance should pay for the vaccines.
