After age 60 the shingles vaccine is recommended. Shingles is caused by the same virus that causes chickenpox. It's recommended even if you don't remember if you had the chickenpox because studies have shown that 99% of people have been exposed to the chickenpox virus. In other words, chances are you had it and don't remember. So, the recommendation from the CDC is to have the shingles vaccine and no need for a blood test to see if you had the chickenpox.
