Global Health Watch: Exec Order Changes Childhood Vaccine Recs, $2B in Faith-based Aid, NIH Restricts Policy Rx

This week, the US Administration announced $2 billion in global health funding for faith-based organizations; US Congress intensified oversight of PEPFAR and the bilateral global health agreements; the NIH moves to restrict policy-focused research; and – perhaps most alarmingly – the US President issued an executive order rewriting longstanding, evidence-based childhood vaccine recommendations.

Global Health Watch: Fauci in Contempt + New NIAID Director, Senate Blocks OMB’s Grant Proposal, New CDC Director, AIDS 2026 Highlights

This week, the US Senate Committee on Homeland Security & Governmental Affairs voted along party lines to hold Anthony Fauci in contempt of Congress for his refusal to answer questions during last week’s hearing on the COVID-19 response testimony – while it was rumored that Steven Quay, a lab-leak proponent, is in line for Fauci’s old job. At the same time, the US Senate Appropriations Committee did step up to stop the White House OMB’s politicization of federal research grants. There’s also – finally – a new leader of the US Centers for Disease Control and Prevention (CDC). And the HIV/AIDS community is unpacking major themes emerging from the AIDS 2026 conference.

AVAC Says Stop the Waste, Fraud and Abuse in the Persecution of Tony Fauci 

AVAC vehemently opposes the decision by the U.S. Senate Homeland Security and Governmental Affairs Committee to hold Dr. Anthony Fauci in contempt for his refusal to answer questions during last week’s hearing on the COVID-19 response. Certain members of the committee have made clear their intentions to pin the shortcomings of the U.S. response to COVID-19 on others by blaming and dragging renowned government scientists and public health practitioners such as Dr. Fauci through politicized proceedings without any evidence and using conspiratorial conjecture.

AIDS 2026: Rising Above to Meet the Moment 

Following AIDS 2026 in Rio de Janeiro, AVAC’s Executive Director Mitchell Warren reflects on a week of conversations, sessions, and new data. As he puts it, Rio was a reminder that science has never been stronger, communities have never been more ready, and the need has never been more urgent. Ending HIV is no longer limited by what we know, it is limited only by the courage to act.

Global Health Watch: Fauci Testifies as AIDS 2026 Wraps Up, Gavi Receives its Funding & New Policy Restricts Gain-of-Function Research

Scientists and advocates gathered in Rio for the 26th International AIDS Conference (AIDS 2026) this week to discuss the future of the HIV response, just as former NIAID Director Anthony Fauci appeared before a hostile Senate Committee on Homeland Security & Governmental Affairs, reminding us that the greatest barriers to ending HIV are increasingly political, not scientific. In addition, this week’s issue covers the US Administration’s use of vaccine funding as leverage in negotiations with Gavi and a new policy restricting gain-of-function research.
