Pellegrini et al., COVID-SHIELD, ACTRN12620000501943, COVID-SHIELD, ACTRN12620000501943, Sep 2020

HCQ for COVID-19

1st treatment shown to reduce risk in March 2020, now with p < 0.00000000001 from 424 studies, used in 59 countries.

Lower risk for mortality, hospitalization, progression, recovery, cases, and viral clearance.

No treatment is 100% effective. Protocols combine treatments.

6,200+ studies for 200+ treatments. c19early.org
