The results are in from the world's largest study of ivermectin for COVID-19.

Researchers in Brazil found that regular use of ivermectin as a prophylactic agent was associated with significantly reduced COVID-19 infection, hospitalization and mortality rates.

The study was conducted in Itajaí, a port city in the state of Santa Catarina, between July and December 2020. Study authors include FLCCC physicians Dr. Flavio Cadegiani and Dr. Pierre Kory. Lead author Dr. Lucy Kerr was approached by the mayor of Itajaí, after the city began to experience a severe outbreak of COVID.

The entire population of Itajaí was invited to participate in the program, which involved a medical visit to compile baseline, personal, demographic, and medical information. In the absence of contraindications, ivermectin was offered as a preventative treatment, to be taken for two consecutive days every 15 days at a dose of 0.2 mg/kg/day.
