This is fascinating and very important. I had no idea there is reliable research on the possible relation between Alzheimer's and vaccines. Thank you.

I see there are different opinions about how long the shingles vaccine is effective, and that there is no booster... another words, you only get to take the (2-part) vaccine once.

What if, 3 years later, you don't tell them you've already had it and go get it again?

Very good questions, and you're right: even the 2-part vaccine lasts only from 4 to 10 years, and I could find no information at all on what to do after that -- only that a "booster" vaccine is not available. I will keep asking and searching! thanks, Mary
