Denmark, the world's biggest producer of mink fur, said Wednesday it would cull all of the country's minks after a mutated version of the new coronavirus was detected at its mink farms and had spread to people. The mutation "could pose a risk that future (coronavirus) vaccines won't work the way they should," Prime Minister Mette Frederiksen told a press conference, adding: "It is necessary to cull all the minks." Danish police estimated that between 15 and 17 million minks would need to be put down. cbw-map/jll/po/pvh
