HIV-prevention drug Truvada approved by US (BBC)

US health regulators have for the first time approved a drug to prevent HIV infection.

Truvada can be used by those at high risk of infection and anyone who may engage in sexual activity with HIV-infected partners, said the Food and Drug Administration (FDA).

Studies showed the drug reduced the risk of contracting HIV by up to 73%.

Some health workers and groups active in the HIV community opposed a green light for the once-daily pill.

There have been concerns the circulation of such a drug could engender a false sense of security and mean people will take more risks. There have also been fears that a drug-resistant strain of HIV could develop.
