Danish Serum Institute is studying mink mutant new coronavirus pneumonia
On November 6, local time, the Danish Radio and Television (DR) reported that the Danish Serum Institute pointed out in a report that five different mink variants of new coronary pneumonia viruses were discovered in Denmark, namely cluster 1—cluster 5.
Preliminary studies have shown that this virus in group 5 is less sensitive to antibodies than non-mutant viruses, which has been proven in laboratory experiments.
This finding is worrying because it may have an impact on the new coronary pneumonia vaccine.
The virus from cluster 1 was also examined using the same method, but no evidence of reduced antibody sensitivity was found.
Other variants (cluster 2–4) are also being tested for sensitivity.
However, these studies will take several weeks because of the need to cultivate viruses.
In Denmark, from early June to mid-October, in 5102 samples, 214 cases of mink mutant new coronavirus pneumonia virus were detected.
The "Cluster 5" virus was found in 5 mink farms and 12 samples in August and September.
Among them, 11 cases were from North Jutland and 1 case in Zealand.
This shows that until now, the infection of mink mutant new crown pneumonia virus is the main problem in North Jutland, which is close to the infected farm.
