From what I’ve read, this virus mutates so frequently that vaccines have been of limited use.
So far, livestock populations seems to be most in danger - not humans.
As is typical with viruses, every mutative step results in a strain that is closer to the foundational virus.
In this case, “the common cold”.
IT’S NO WORSE THAN REGULAR FLU. Had it back in my dairy farm days. Farmers are subject to almost anything, but they seldom panic. They don’t pay much attention to viruses or flu. The animals have to be tended to.
