In her piece for the University of Pennsylvania Leonard Davis Institute of Health Economics, Tachibana talks with researchers and health care providers about evidence-based methods for making this lifesaving medication easier to access, especially for the most vulnerable people. Providing nonjudgemental information about PrEP via trusted messengers and as part of routine sexual health care could help increase uptake, she reports, as could increasing the use of telehealth services to prescribe it.
