During the first webinar of a three-part series, speakers provided an overview of the World Health Organization’s 2020 guidelines on voluntary medical male circumcision (VMMC) for HIV prevention, the process used to develop the guidelines, and the evidence considered on the impact of VMMC on HIV incidence among men, women, and communities. The presentations from this 21 August 2020 webinar are available in one document. Additional presentations — one on the guideline development process and another on modelling the impact of VMMC in HIV prevention — are also available with audio. Listen to the entire webinar in English or Portuguese.
