A.D.
She caught the virus - therefore she's had it and should be immune, I wouldn't have her get it either. I know the vaccination booster is supposed to be required for all school children this fall but seems unnecessary for her. I was bothered by this, so I actually went to the Texas Immunization Branch under the Department of State Health Services and it falls under the FAQ's. The link is at the end of the question.
20. If a child has had chickenpox illness is he/she required to get the vaccine?
No. If a child has had chickenpox at any age, he is not required to get the vaccine. Documenting history of chickenpox illness must include a written statement from a physician, school nurse or the child's parent/guardian containing wording such as: "This is to verify that (name of child) had varicella disease (chickenpox) on or about (month/day/year) and does not need the varicella vaccine."
