Global Health Watch: Assault on US vaccine policy, contradictions in HPV and HIV vaccine science; 14 countries sign America First MOUs

At the same time, the US President signed a new executive order withdrawing the US from and defunding over 60 international organizations and treaties.

Global Health Watch: UNAIDS launches review, NIH GoF controversy, support for IDSA’s Jeanne Marrazzo, UK authorizes LEN for PrEP

This week the UNAIDS board approved a new Global AIDS Strategy and launched a formal review of the agency’s future; turmoil at the NIH continues over gain-of-function research; and the scientific community rallies around the Infectious Diseases Society of America’s (IDSA) appointment of Jeanne Marrazzo as its chief executive officer. Also, the UK regulatory agency approved lenacapavir for PrEP (LEN) marking its seventh regulatory approval in just six months.

We’ve been able to do this work because of your partnership and support, and we are deeply grateful.

The Future of HIV Prevention Depends on Speed, Scale and Equity 

We are in a golden moment, where innovation, evidence and opportunity align. But proposed funding cuts could undo everything. These aren’t abstract numbers on a page. These cuts would shutter clinics, slow prevention, restrict treatment, and roll back the very systems that allow new tools like LEN to reach people.

Track the Science; Advance the Priorities

The People’s Research Agenda sets out a people-centered framework for equitable and accelerated R&D and product introduction. It tracks the science, shows where investments align—or fail to align—with community-defined priorities, and spotlights critical gaps in the pipeline of prevention options needed to meet the diverse realities of all populations.
