"The virus produced by the mink mutation, on the other hand, seems impervious to antibodies produced in response to the dominant strain of the virus. What makes this mutation so much more troubling than previous mutations is not that the mutation increases how quickly the virus will spread, nor that it increases the severity of resultant disease. It’s the fact that the immune system cannot transfer knowledge about one form of the virus in fighting the other form. From the perspective of your immune system, they are two different viruses altogether.
In other words, if you have survived COVID-19, your immune system remains largely unequipped to battle the mink strain. Once pharmaceutical companies finish their months-long race to devise an effective COVID vaccine, the vaccine would likely provide little protection against the emerging strain. The virus has mutated into what could eventually be thought of as COVID 2.0 if the Danes fail to contain its spread."
