Project SOAR: robust evidence to improve the global HIV response

Recent advances in the global HIV response hold great promise for ending the epidemic. Project SOAR implementation science research generates insights to inform and improve the provision of life-saving HIV prevention and treatment. This PLOS Collection presents SOAR research that evaluates innovative service delivery approaches, models cost and impact, and elucidates social barriers to care.


This collection is a work in progress. As each article is published, we will add it to this page. To view the Collection on the PLOS site, please go to:


Drs Scott Geibel and Eileen Yam introduce the collection in a PLOS Blog. (Read blog on PLOS site)
