Good news this week on the AIDS front, with mild success reported from a vaccine trial. See David Brown's reporting on it in the Washington Post.
The trial involved more than 16,000 men and women in Thailand, and it cost $105 million. Most of that came from the United States' National Institutes of Health, through the National Institute of Allergy and Infectious Disease.
Just for the record, the entire NIH budget is counted as health care spending by US residents when those tabulations are made of the percent of GDP that we spend on health care.
