A survey by the United States Office of Technology Assessment (OTA) indicates that conflict continues in the medical community over the proportion of the biomedical research budget allotted to AIDS (acquired immunodeficiency syndrome). Regardless of their views on that issue, most researchers believe that AIDS research has important consequences for other research fields. Almost half of the 148 respondents to the OTA survey 'agreed' or 'strongly agreed' that too much funding had gone to AIDS research at the expense of other fields, but the other half disagreed. Currently, the National Institutes of Health spends about 10 percent of its $7,100 million budget on AIDS-related research. This is more than is spent for heart disease, and close to the amount spent for cancer, both of which cause more deaths than AIDS. However, most respondents to the survey questions felt federal spending on AIDS was appropriate, or too low. This can be interpreted as a sentiment that spending on biomedical research, overall, is too low. More than half the respondents also believed that AIDS research has led to advances in virology, immunology, and molecular biology, while also promoting the development of diagnostics and new drugs. Flexibility was introduced into the AIDS funding procedure by Congress in 1989; NIH directors are now allowed to reallocate AIDS research monies to other areas when they consider it advantageous.
