PrEP and the Role of HIV Self-Testing
HIV self-testing (HIVST) is a safe, accurate, and effective alternative to provider-administered testing that many users prefer for its convenience and confidentiality. At IAS 2023, WHO issued a new recommendation to offer HIVST for PrEP initiation and continuation as an innovative way to increase PrEP access and coverage and further simplify PrEP delivery. However, many implementers still have questions on how to effectively roll out and scale up this important self-care intervention.
On May 23, AVAC and WHO hosted a webinar to learn more about WHO guidance on use of HIVST and to hear directly from a panel of experts on their experiencing rolling out HIVST for PrEP, guidance on procurement and costing, and more.

For Us by Us: PrEP in Black America – A Master Plan for HIV Prevention in Black America
In the spirit of seeking change to ameliorate the devastating impact of HIV in Black communities through biomedical HIV prevention, Black leaders convened the “PrEP in Black America (PIBA) Summit” virtually and in person on September 13, 2022, in Atlanta, Georgia. Attendees have included Black activists, researchers, scientists, providers, and policymakers from across the country representing more than 50 organizations. Following the event, PIBA generated a report summarizing the event and key recommendations entitled, “For Us by Us: PrEP in Black America – A Master Plan for HIV Prevention in Black America.”

The More We Know
Science and real-world experience continue to demand a re-assessment of our collective understanding of the safety and effectiveness of PrEP options for women, including oral, vaginal ring, and injectable options. For instance, a new paper in the Journal of the American Medical Association by Dr. Jeanne Marrazzo (HIV Pre-Exposure Prophylaxis with Emtricitabine and Tenofovir Disoproxil Fumarate Among Cisgender Women) challenges the notion, baked into policies, programs and “conventional wisdom”, that cisgender women need to be “super-adherers” to achieve protection utilizing oral PrEP. In this webinar, we discussed this important paper and more.

The Importance of HPV Vaccination Among People Living with HIV
HPV vaccination prevents 6 types of cancer and genital warts, including cervical cancer. Women living with HIV are up to six times more likely to develop invasive cervical cancer than their HIV-negative peers, but HPV immunization rates among this population remain low. During World Immunization Week, AVAC and TogetHER for Health co-hosted a discussion to learn more about the science behind and implementation challenges specific to expanding access to HPV vaccination for people living with HIV.

This webinar was co-hosted with TogetHER for Health
