US-FDA approves HIV prevention drug

The US Food and Drug Administration has approved a drug that helps prevent HIV infection. The drug, called Truvada, is mainly meant for high risk people, most especially those who have sex with partners already infected by HIV. Research shows that the drug can reduce risk of infection by 75%, but the drug is expensive – costing as much as $11,000 per year. Advocates say the challenge now is to get the drug to groups who can’t afford it. Another group warns of the dangers of those already infected with HIV taking the tablet, saying it might develop new HIV strains that are resistant to the drug.
