It found a highly significant 75% reduction in covid mortality, based on randomized controlled trials only, and will be continually updated with additional trial results.To date, the mode of action of ivermectin against SARS-CoV-2 has remained somewhat of a mystery. Early studies indicated that ivermectin may inhibit viral protein transportation. But a new US-Canadian study, published in Nature Communications Biology, found that ivermectin is highly effective (>90%) in inhibiting the main...
