US approves cheap generic version of breakthrough HIV prevention jab – in major step towards ending Aids
The FDA approved a generic version of Gilead Sciences' HIV prevention jab Lenacapavir, developed by Dr Reddy’s Laboratories. The generic costs $40/year, significantly less than the original $28,000/year price. It will be available in 120 low- and middle-income countries, with Zambia expected to receive supplies first. The approval is seen as a step towards ending the AIDS epidemic by 2030, but funding cuts and supply constraints remain challenges.
