I went there and they told me the same thing. I am 66, and I asked if I could get despite the lack of evidence. The Dr. said yes, so some doctors might be flexible? He said it might not prevent it, but if you get it, the symptoms might be less severe. Who knows. Might prevent it, might make it less severe, might not. I got it anyway. No side effects. I got the Shingles vaccine at the same time. One in one arm, one in the other. The Shingles arm was sore for days.
