Just a little info re Shingles vaccine. I had Shingles in Sept. 2009. In Oct. 2011, I had the vaccine. In Sept. 2012, I had Shingles again. The only good thing about the vaccine is that 'if' you get the Shingles after having the vaccine, it won't be as bad as if you had not had the vaccine. My DH had the vaccine in 2009 after I came down with Shingles and has not had a case. And, yes stress does play a roll in the eruptions. Jinnie
