Do you recommend the shingles vaccine I am 63 years old and don 't know if I ever had chicken pox.?

Recommended. It is a good chance that u had chickenpox when u were a youngster. Some had the infection but never had the rash (subclincal diseasr). Zostavax is a live-virus and is effective against shingles, and chickenpox too. The risk of vaccination is small and the benefit can be significant. So, consult your doc for the vaccine, recommended for 60-yrs young and beyond. Good luck.
Yes. “Healthy adults 50 years and older should get two doses of Shingrix, separated by 2 to 6 months. You should get Shingrix even if in the past you: had shingles, received Zostavax, are not sure if you had chickenpox. There is no maximum age for getting Shingrix.” REF: https://www.cdc.gov/vaccines/vpd/shingles/public/shingrix/index.html.
