I am seeing ads on the TV recommending vaccination against shingles. This puzzles me a bit, because when I trained, the wisdom was that if you had chicken pox as a child, you were unlikely to have shingles as an adult because you were primed. I just checked my old Merck manual and it says something along the lines the “Herpes simplex tends to recur, but Herpes zoster rarely does”. So sometime in the last 20 years or so, the advice has changed to “anyone who has had chicken pox can get a recurrence as shingles”. I think it was previously, if you get H. zoster as a child it manifests as chicken pox, if you get it as an adult (having not had it as a child) it manifests as shingles. Can anyone place when this was changed?
I’ll do some checking in the literature. But I thought I’d put it up here because I think it’s Quite Interesting.
