How dangerous can mutated coronavirus strains be?

Synopsis

Mutated strains of the coronavirus, particularly one identified in minks, have raised significant public health concerns. This strain, which affects the virus's spike protein-the primary target of most vaccines-has led to mass culling in Denmark, where the outbreak has been most severe. The situation escalated politically, resulting in the resignation of Denmark's agriculture minister after the government acknowledged it lacked legal grounds for the nationwide culling. Mink farmer Bjarna Pedersen shares the impact of the virus on his herd, emphasizing the ongoing threat of coronavirus mutations.
