The Skoll World Forum and the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog have co-produced a blog series to answer the question, “What will it really take to end AIDS?” In the first of six posts, Steffano Bertozi, director of HIV in the Gates Foundation’s Global Health Program, writes, “[D]espite evidence of measurable progress, it’s important to recognize that we still don’t have all of the tools that we need to end AIDS,” therefore “we still have an essential moral obligation to discover, develop and deliver new and better ways to help people protect themselves from HIV infection” (12/3). In another post, Erin Hohlfelder, ONE’s policy manager for health, says with “scaled-up financing, targeted programming, and expanded political will,” as well as “renewed urgency and concerted action, the world can transform the beginning of the end of AIDS from a vision to a reality and chart a course towards ending this pandemic” (12/3).
