Randomized Controlled Trial
Fold rise in antibody titers by measured by glycoprotein-based enzyme-linked immunosorbent assay is an excellent correlate of protection for a herpes zoster vaccine, demonstrated via the vaccine efficacy curve.
The phase III Zostavax Efficacy and Safety Trial of 1 dose of licensed zoster vaccine (ZV; Zostavax; Merck) in 50-59-year-olds showed approximately 70% vaccine efficacy (VE) to reduce the incidence of herpes zoster (HZ). An objective of the trial was to assess immune response biomarkers measuring antibodies to varicella zoster virus (VZV) by glycoprotein-based enzyme-linked immunosorbent assay as correlates of protection (CoPs) against HZ. ⋯ NCT00534248.

Randomized Controlled Trial
Responses to A(H1N1)pdm09 influenza vaccines in participants previously vaccinated with seasonal influenza vaccine: a randomized, observer-blind, controlled study.
Prior receipt of a trivalent seasonal influenza vaccine (TIV) can affect hemagglutination inhibition (HI) antibody responses to pandemic influenza vaccines. We investigated the effect of TIV priming on humoral responses to AS03-adjuvanted and nonadjuvanted A(H1N1)pdm09 vaccines, the role of AS03 on cell-mediated immune (CMI) responses, and vaccine safety. ⋯ Clinical Trials.gov identifier NCT00707967.
