Abstract
The United States has for decades been a great benefactor of global science. Last year, the US National Institutes of Health (NIH) awarded hundreds of grants to researchers outside the country. In 2022-23, the country supplied about 42% of the overall donor-government assistance for global health and about 16% of the World Health Organization's (WHO) funding. During the COVID-19 pandemic, it bankrolled a fair share of the global public vaccine effort.
