The United States’ National Institutes of Health (NIH) has officially lifted its ban on South Africa, reversing a decision that had halted funding for critical research initiatives in the country. The US began suspending funding for South African projects, including NIH grants and US Agency for International Development (USAID) aid, in January 2025. This suspension marked a significant change in the long-standing collaboration between the two nations on health research. A memo from the NIH, which formally rescinded the ban, explicitly stated that its grants are “distinct from the objectives traditionally associated with foreign aid or assistance,” indicating a key shift in policy regarding research funding in South Africa. The decision to lift the ban comes nearly 18 months after the initial order to stop work with the country was first issued.
Impact of the Ban
The consequences of the funding suspension were broad and immediately felt by the scientific community. Médecins Sans Frontières (Doctors Without Borders), the US advocacy organisation Treatment Action Group, and the South African Medical Research Council (SAMRC) reported that critical research initiatives and decades of investment in research infrastructure were severely affected by the NIH stop-work order. These organizations collectively found that the ban jeopardized significant progress. Research conducted in South Africa, primarily led by South African scientists with NIH funding, has in the past two decades significantly shaped global health policies. These policies have been instrumental in revolutionizing TB and HIV prevention, diagnosis, treatment, and care, benefiting both the local population and communities worldwide, including people who live in the United States. The cessation of funding thus posed a threat to ongoing advancements in these vital areas. Additionally, the Fogarty International Center, another key player in international health research, had ceased supporting research training and career development applications from South Africa. This particular decision stemmed from South Africa's classification as an upper-middle-income country, which altered its eligibility for certain types of international support.
Rescue Efforts and Funding
In response to the critical funding shortfall, in August 2025, the South African Medical Research Council (SAMRC) announced a significant intervention. The SAMRC revealed it had successfully secured approximately R600 million in rescue funds. These key funds are specifically designated to support research projects and groups that were negatively impacted by the cuts imposed by the NIH ban. The R600 million rescue fund comprises contributions from several prominent organizations, noting a collective effort to safeguard vital research. National Treasury provided around R400 million, demonstrating a substantial commitment from the South African government. Additionally, the Gates Foundation and the Wellcome Trust each contributed R100 million, showing their dedication to global health research. An additional R14.4 million was received from the ELMA Foundation, further bolstering the rescue efforts.
Expert Reactions and Outlook
The National Institutes of Health (NIH) officially lifted its ban on South Africa nearly 18 months after an order to stop work with the country was first issued. An internal memo, dated August 17 and signed by NIH director Jay Bhattacharya, formally rescinded the ban, allowing for the immediate resumption of critical research collaborations. This decision reverses a previous policy that had halted funding for numerous projects, bringing a sigh of relief to researchers and public health advocates alike. The lifting of the ban is expected to allow for the continuation of new work that has historically contributed to global health advancements, particularly in the fight against HIV and TB.
