One choice could possibly be “voluntary licensing,” the place different corporations are granted permission to supply and promote generic variations of a patented product solely to folks in sure (usually low-income) nations. Researchers on the College of Liverpool within the UK have calculated {that a} 12 months’s price of lenacapavir could possibly be made accessible for as little as $25.
