Yes (see my above post for more info as well). In the US we have about 3-4,000 cases of meningiococcial infections a year. Are most common serogroups are A, Y and B, IIRC. Even treated meningiococial meningitis (well really all bacterial meningitis) has a mortality rate somewhere between 10-20%, which is scary high. Think about that, that means that even despite aggressive medical treatment potentially 1 in 5 people that get it will die anyway.
Ifink, iirc, parts of Europe have larger problems with group B than we have here in the states. And I remember that in other parts of the world meningiococcial infections are as high as 17-20 per 100,000 (vs the 1-2 per 100,000 we have in the US).
So yes, this is a good thing and will save many lives. I just hope it gets licensed in the US. The FDA is pretty stingy about licensing vaccines developed in other countries here, even ones in the EU and even ones with lots of evidence supporting their use
