CDC recommends those at risk take daily pill to prevent HIV infection

Fighting infection

Daily pill is recommended to prevent HIV

Officials at the U.S. Centers for Disease Control and Prevention recommended Wednesday that hundreds of thousands of Americans at risk for AIDS take a daily pill that has been shown to prevent infection with the virus that causes it. The CDC's advice could transform AIDS prevention in the United States from reliance on condoms to a regimen that relies on an antiretroviral drug, Truvada. It costs $13,000 a year, and most insurers already cover it. While the CDC endorses the drug only in conjunction with condoms, health officials say some people will likely stop using condoms.

NIH: End sex bias in early studies

Amid growing evidence that many drugs are not as effective in women as in men, the National Institutes of Health warned scientists Wednesday they must include female lab animals and female cell lines in their research. A commentary outlining the NIH's new policy was published in the journal Nature. Although women respond differently than men to a broad array of treatments, from aspirin to anesthesia, and often do not derive the same benefits as men do, it has long been a staple of basic research that female animals make poor subjects because their menstrual and hormonal cycles may skew test results. As a result, many scientists have tested their theories only in male lab rats or in male tissues and cells.
