Okay, I just read this article.

The girl that died-came from Switzerland. A guy was just released as "healed" from the Hospital. The Baby is doing better and they are not fearing for it's life, on the way to getting better.
The article is pretty matter of fact-no panic. They don't mention the baby's age, vax status, anything. 9 people who could have had contact with the baby were preemptively treated with antibiotics.
None of the sick had contact among each other.
I really would not be too worried. Berlin (there is an official number of people living there-and an unofficial number) has it's fair share of infectious disease, sometimes meningitis and sometimes weird things like Malaria (not infectious- I just mentioned it among the colourful disease you find on ocassion), people coming back travelling. Every once in a while you hear something like yellow fever, but in my 20 years of living there-don't worry too much.
Do you read and speak German?
Wiki has an excellent article on Neisseria, much better than the english one.
