Q: I’m 65, and my doc says I’m overdue for my shingles vaccine. I hear it’s a tough one to tolerate, so I’ve been putting it off. Then she told me it also helps protect against stroke. How does that work? — Cam E., Memphis, Tennessee

A: First of all, the shingles vaccine is generally safe, even though some people get flulike symptoms (headache, fatigue), a skin rash and/or joint pain that can last a day or two. But the vaccine side effects are nothing compared with the notoriously painful short- and long-term consequences of a shingles attack (nerve pain that can last for months or years).
