Research Fundamentals: What is partial protection?

July 22, 2020

Px Pulse Logo

AVAC is launching a new series on our podcast Px Pulse—Research Fundamentals. In addition to our regular schedule of programs covering advances and challenges in HIV prevention research, Research Fundamentals we’ll explore scientific concepts in research, one at a time.

In our debut episode we explore the concept of partial protection, with:

  • David Evans, science and advocacy consultant for AVAC, formerly of Project Inform
  • Penny Moore from South Africa’s University of the Witwatersrand and National Institute for Communicable Diseases
  • And Sandhya Vasan of the US Military HIV Research Program

Together we explore the meaning of partial protection. Whether it’s condoms, a flu shot, oral PrEP or the dapivirine vaginal ring, proven products fall short of 100 percent protection against disease, and there’s a lot to know about how and why an intervention may offer imperfect but still useful protection.
