The coronavirus mutation found in Danish mink farms is not so scarry

 "The coronavirus mutation found in mink farms in Denmark that subsequently infected humans is unlikely to reduce the effectiveness of a potential Covid-19 vaccine, experts said after reviewing published data.

Danish experts said they found no clear concern that the vaccine would be less effective against the variant coronavirus "Cluster 5" found in mink. Recently, the Danish government decided to slaughter all the minks in the country, amid concerns that a mutated form of the coronavirus could hamper use of vaccines. The decision was made on the basis of preliminary results from the "Cluster 5" mutation tests performed by the national infectious disease agency, SSI."

This is not to say that there are no problems for mink growers. These animals are kept in pens with a large number of animals in one place. The coronavirus spreads between them like a fire in a dry forest. A typical trouble of intensive farming these days.
