Covid-19 mink variants discovered in humans in seven countries
Denmark has already launched a nationwide cull of its farmed mink herd after concerns for vaccine efficacy
Seven countries are now reporting mink-related Sars-CoV-2 mutations in humans, according to new scientific analysis.
The mutations are identified as Covid-19 mink variants as they have repeatedly been found in mink and now in humans as well.
Uncertainty around the implications of the discovery of a Covid-19 mink variant in humans led Denmark, the world's largest mink fur producer, to launch a nationwide cull earlier this month.
The cull was sparked by research from Denmark's public health body, the Statens Serum Institut (SSI), which showed that a mink variant called C5 was harder for antibodies to neutralise and posed a potential threat to vaccine efficacy.
