Meta analysis of 11 HCQ PrEP studies in India covering 7,616 healthcare workers, showing significantly lower cases with treatment.

7 meta analyses show significant improvements with hydroxychloroquine for mortality Landsteiner de Sampaio Amêndola, Risch, Risch (B), Stricker, hospitalization Landsteiner de Sampaio Amêndola, recovery Prodromos, combined death/hospitalization/cases Ladapo, and cases García-Albéniz.

Currently there are 99 HCQ for COVID-19 pre-exposure prophylaxis studies, showing 30% lower mortality [12‑44%] and 29% fewer cases [21‑37%].
