Had 2 definite cases of chickpox at 5 & 16. will my child's vaccination cause me to get it again or shingles? had it twice, i fear my immunity is low.

Should be OK: You should have natural immunity at this point but if you want to be sure have your doctor test your varicella antibody titre to see if you have protection. If not, get the vaccine yourself. Your child's vaccination should not affect you. Anyone who has had chicken pox in the past or the vaccine can get shingles at any time in their life.
