NCT01262300

Brief Summary

This is an ancillary study to a randomized controlled trial of high dose vitamin D in older long-term care residents (NCT01102374). In this study, a subset of trial subjects will receive the zoster vaccine and the investigators will determine the immunological response to the vaccine in this older, frail population, as well as the association between vitamin D and immunological outcomes.

Outcome Measures

Primary Outcomes (1)

  • VZV-specific cell mediated immunity, as measured by the interferon-γ ELISPOT assay

    3 weeks post-vaccination

Secondary Outcomes (3)

  • VZV-gpELISA to measure the VZV-specific antibody concentration

    3 weeks post-vaccination

  • VZV-specific effector and memory T cells

    3 weeks post-vaccination

  • -specific cell mediated immunity, as measured by the responder cell frequency assay

    3 weeks post-vaccination

Study Arms (1)

VZV vaccine

EXPERIMENTAL

Varicella Zoster Virus vaccine (Zostavax), single dose X 1 injection All subjects in this trial will receive the VZV vaccine. The Investigators will primarily compare immune responses in those that are receiving high dose vs. standard dose vitamin D supplementation and those that have high and low 25-hydroxyvitamin D levels.

Biological: Varicella Zoster Virus Vaccine (Zostavax)

Interventions

Single 0.65 mL subcutaneous injection of the live, attenuated VZV zoster vaccine (Zostavax; Merck, Whitehouse Station, NJ).

VZV vaccine
