Millions of minks globally have contracted COVID-19, leading government officials to call for the animals’ culling to prevent the virus from mutating, potentially reinfecting humans, or thwarting vaccination efforts.

Last week the World Health Organization launched an investigation into virus transmission on mink farms because researchers had identified one mutation labeled D614G in the spike protein of the virus that may increase transmission. There is no evidence so far that the mutation would increase virulence. It also “does not appear, at this point, that that mutation that’s been identified in the minks is going to have an impact on vaccines and affect a vaccine-induced response,” noted Anthony Fauci, the director of the US National Institute of Allergy and Infectious Diseases, during a November 12 webinar hosted by the think tank Chatham House.

Humans did initially inadvertently introduce the virus into mink farms, according to an analysis of ...
