They just haven't told you yet.
The thing is fairly mild, but can still lead to complications in the elderly or others with underlying conditions. It is starting to slowly go H2H...
The latest flu vaccine does not cover this strain, although to get it may protect from H3N2 recombining in you with a different strain. This flu strain is new and not really understood. As usual and normal, flu strains can and do mutate.
A further problem down the road will be the chance for this flu to combine with a stronger strain such as but not limited to H5N1. No need to panic, just remain aware of it. I don't advocate a flu vaccine or offer medical advice, just trying to keep you appraised of the situation. My family took the previous H1N1 vaccine without any side effects and did not catch that or any flu in 2009...just sayin.
