Dose-response relationship of DNA and recombinant fowlpox virus prime-boost HIV vaccines: Implications for future trials

Abstract

Estimating effective doses of novel HIV vaccines is challenging. Dose-response analyses of DNA and fowlpox virus HIV vaccines showed that 1 mg of DNA vaccine and 5 × 107 pfu of fowlpox virus booster was immunogenic in macaques. However, this dose was poorly immunogenic in humans. When adjusted for body surface area, the human dose studied was equivalent to a poorly immunogenic lower dose in monkeys. These data provide a rationale for guiding dosing in future trials of HIV vaccine technologies. ©2006 Landes Bioscience.
