DEAR DOCTOR K: You've written about who should get the shingles vaccine, and why. Are there any groups of people who should not get the shingles vaccine?
DEAR READER: I'm glad you asked because, yes, there are groups of people who should not get the vaccine. Shingles is a painful skin rash, often with blisters, that lasts from two to four weeks. Its main symptom is pain, which can be quite severe. For some people, the severe pain of shingles continues long after the rash clears up. Called post-herpetic neuralgia, this condition can last for months, or even years. It can be quite debilitating.
