Oh, you not got main message. Worse is: human body does not produce IgG antibodies to this "mink virus". That means it is not possible to make vaccine against this mutation (in article they write calming "the effectiveness of any future vaccine could be affected by the mutation", but pay attention to word "any"), BUT MAIN is: you may be sick by this virus many times case by case, because you will have no immunity (no IgG). And that is very serious. That why Denmark kills all minks in country and isolate 12 persons who are sick with this mutation.
