A U.S. funding freeze halted a major African HIV vaccine trial in 2025, disrupting years of research.
A major HIV vaccine trial across Africa was halted in 2025 after a U.S. executive order froze foreign aid, cutting off $45 million in USAID funding.
The trial, aimed at developing a vaccine tailored to diverse African HIV strains, had been nearing launch following years of research and a key planning meeting in Zanzibar.
Scientists, including Penny Moore and Linda-Gail Bekker, were devastated by the sudden stoppage, which disrupted progress built on decades of data from South African women.
Despite the setback, researchers remain hopeful, citing advances in understanding HIV’s behavior and ongoing efforts to restructure the trial with international collaboration and alternative funding.
