It would seem enormously critical to know how well the immune response from developed vaccines deals with this strain. Given they are are mostly targeted against the spike protein and the bulk of the mutations of the new strain are within the spike protein (in some cases are directly associated with evading human immune response), it seems possible (even if unlikely) that it might significantly reduce their effectiveness. I wonder how quickly this can be experimentally established?
