To define the phenotypic characteristics and kinetics of T cell responses to a shingles vaccine in elderly individuals, 20 subjects > or =60 years of age received two doses of vaccine or placebo 6 weeks apart. VZV-specific T cell phenotypes and intracellular cytokines were determined by flow cytometry on blood mononuclear cells obtained pre-vaccination and up to 6 months after the second immunization. Results were compared with responses of five unvaccinated young adults. Pre-vaccination, elderly individuals had significantly lower VZV-specific effectors and cytokine-producing T cells compared with young adults. The vaccine significantly increased VZV-specific Th1, memory, early effector, and cutaneous homing receptor-bearing T cells.
