Response to the varicella vaccine in children with nephrotic syndrome.

Varicella vaccine was administered to seven children with corticosteroid-sensitive nephrotic syndrome. Immunization was not associated with any significant reactions or with increased frequency of relapse. The antibody response was, however, variable and a second dose was necessary before seroconversion was achieved in four patients. The findings indicate that immunization with varicella vaccine is safe in children with nephrotic syndrome in remission, but that a two-dose vaccine schedule should be considered.
