In the fourth installment of AVAC’s webinar series on COVID-19 and its relationship to HIV, John Stover, Vice President and founder of Avenir Health, will discuss the current state of COVID-19 modeling. Mr. Stover will be joined by his Avenir colleagues Katharine Kripke and Nadia Carvalho, who will also discuss a new learning opportunity for advocates wishing to use modeling in their work. This online course was developed by Avenir as part of the Coalition to Accelerate & Support Prevention Research (CASPR) led by AVAC and supported by USAID.
