One dose is not enough, the recommendation is 2 doses 1 at age 1 year & 2nd at age 4-6 years before entering kindergarten. If he is immunized there no risk of catching chickenpox from a patient with chickenpox or shingles unless the child is immune compermised. So go ahead make appointment with her pediatrician to get her boosters. Good luck

They estimate 85% success with 1 but having a 2nd dose no sooner than a month from the first brings that up to >95% protection.Only the actual drainage/debris from zoster sores have germs in it, so being in a persons vicinity does not place them at any risk, even if never vaccinated.

prior to going to school he definitely needs a varicella vaccine booster to maintain his immunity we are now giving a third varicella vaccine dose in adults to prevent adult onset shingles the virus lives in the nerves and becomes active when antibodies decrease.hence the third adult dose exposure to shingles does not increase chance of shingles in your child
