In a statement issued 7 November, the World Health Organisation (WHO) reported that a Covid-19 mutation had been detected at mink farms in several countries, including Denmark, the Netherlands Spain, Sweden, Italy and the US.

Speaking about the new strain of Covid-19, called « Cluster 5 », the WHO said « severity and transmission among those infected are similar to that of other circulating SARS-CoV-2 viruses », but it might have « moderately decreased sensitivity to neutralizing antibodies ». Therefore, this could undermine the effectiveness of any future vaccine against Covid-19. Furthermore, the WHO said that « the implications of the identified changes in this variant are not yet well understood ».

In Denmark, 12 people have been found to have the new mink-related strain of the virus in the northern tip of Jutland. 4 November, Danish Prime Minister Mette Frederiksen had ordered the slaughter of all herds of mink throughout the country following the discovery of the new strain.

Meanwhile, 9 November pharmaceutical companies Pfizer (US) and BioNTech (Germany) announced that they had developed a vaccine 90% « effective » at protecting from Covid-19 infections according a current major test, which is the last stage prior to requesting official approval. We remind you that no Covid-19 vaccine has been officially validated as yet for mass commercial distribution.
