After detecting variations of Sars-CoV-2 in more than 200 people, a Danish infectious disease center fears that the new mutations will be more resistant to the future Covid-19 vaccine
According to information released on Friday, 6, a mutation of the new coronavirus was detected in 214 people in Denmark. The discovery was made by the Statens Serum Institut, a reference center for infectious diseases in the country. The agency said that these variations “show a reduced sensitivity to antibodies from several people with previous infections”, which could mean that “a future vaccine will be less effective”.
Aware of these discoveries, the World Health Organization (WHO) said, also on Friday, that it considers it too early to assess the consequences of a variation of the new coronavirus because “there is no evidence of impact on the spread of the pathogen or the severity of the infection”. The agency’s experts indicate that mutations in a virus are normal and that Sars-CoV-2 itself has undergone several since it started spreading around the world in late 2019.
Five mutations of the coronavirus had previously been detected in Denmark, only in mink, small mammals similar to weasels that are raised on farms to manufacture fur coats. Denmark even announced on Wednesday that it would sacrifice 17 million of these animals precisely to prevent new versions of Sars-CoV-2 from harming the effectiveness of vaccines that are currently being developed.
However, the Statens Serum Institut pointed out that “infection among mink farms is increasing in number and geographic extent, without the preventive measures having worked.” The institute also warned that the coronavirus mutation was not found only in people working on mink farms, but in the general population.
