What could be though is:
The immune system is busy mounting its primary response to the vaccine, the host
meets a different strain of the virus shortly after (i.e. when still responding
to the vaccine). Thus, most of the early adaptive immune system is targeting one
stain and the other may have more space in which to proliferate and hence cause
infection. Hence the new strain has become established before the immune system
recognises it is there.
