One possibility may very well be “voluntary licensing,” the place different firms are granted permission to supply and promote generic variations of a patented product completely to individuals in sure (usually low-income) international locations. Researchers on the College of Liverpool within the UK have calculated {that a} 12 months’s value of lenacapavir may very well be made obtainable for as little as $25.
