Am guessing this is one step nearer more concerning potential vaccine protection issues. The continuation of the Mu iteration could 'up the ante' too, I guess, if any kind of combination was to happen between the two flavours.

Arguably, it's likely it's this that has had a greater impact on the development of this disease up to now than vaccinations.
