New HIV drug 100% effective – but why does it cost $40,000?

If you had the tools to fight a disease that kills 630,000 people a year – would you share them?

Scientists at the world AIDS conference in Munich have revealed that a groundbreaking new drug to prevent HIV infection – marketed at $40,000 per person – could be made for just $40.

Trials show that the twice yearly injection – from pharmaceutical giant Gilead – is 100% effective against HIV.

Gilead has not told us how much they spent on developing or purchasing the drug. But the current price puts it out of reach of those who would benefit most.
