In 2024-2025, the Gates Foundation was the largest voluntary contributor to the World Health Organization (WHO), accounting for over 13 percent of all voluntary contributions at that time, followed by GAVI, the Vaccine Alliance. In January 2025, U.S. President Trump signed an executive order withdrawing the U.S. from the WHO, which came into effect as of February 2026. The impact of such a withdrawal on the WHO is difficult to predict, but it will likely have implications for public health around the world, including the United States itself.
