Seven doctors who gathered at a COVID anti-vaccination summit in Florida to tout the anti-parasitic drug ivermectin and other alternative measures for preventing the transmission of the coronavirus now have contracted COVID-19, The Daily Beast reported on Tuesday. One of the doctors — Dr. Bruce Boros — is from the Florida Keys. Boros, of Key West, told the Miami Herald in September 2020 that he had been giving ivermectin — commonly used as a dewormer for cows, horses and other livestock — to COVID patients.
