, Galveston, showed evidence of a direct anti-viral effect of Interferon alpha against novel Coronavirus in vitro. The study demonstrated around 10,000 fold reduction in the quantity of virus that was pre-treated with Interferon alpha 48 hours earlier. A second study by universities in China, Australia and Canada analysed 77 moderate COVID-19 subjects in Wuhan and observed that those who received Interferon alpha-2b showed a significant reduction in the duration of virus shedding period and even in levels of the inflammatory cytokine, IL-6. This drug is also used off-label in cats and dogs, both by injection and orally. The cross-species nature of IFN-α allow it to work in non-human animals, but the period of usefulness is limited by the production of antibodies against this foreign protein.
