How much money was spent on aids research last year?

As of my last knowledge update in October 2021, I do not have specific data on the amount spent on AIDS research in the previous year. However, funding for HIV/AIDS research typically comes from various sources, including government agencies like the National Institutes of Health (NIH), non-profit organizations, and private sector investments. For the most accurate and current figures, it is best to refer to reports from relevant health organizations or government publications.
