If you have had chicken pox, you’re at risk for shingles. Risk increases with age (starting at 50). ACIP says everyone 60 and older needs vaccination, unless there’s a contraindication. The only zoster vaccine currently available (brand name Zostavax) is a live virus vaccine so it can’t be given to people with immune system problems or to anyone who’s pregnant. Zostavax overall cuts the risk of getting shingles in half. There’s a new adjuvant herpes zoster subunit vaccine (HZ/su) under study. It’s not yet available; so it is not mentioned in the schedule, but a recent study in NEJM (http://www.nejm.org/doi/full/10.1056/NEJMoa1501184#t=article ) says it cuts risk of shingles by more than 97%. It is likely zoster vaccination recommendations may change if or when this new vaccine is licensed by FDA.
