While its probably higher than flu, the actual rate is just a guess atm, since they have no idea how many mild cases go unreported, and therefore not counted.

As I understand it, the vaccine is made up of the strain that they think will most likely be doing the rounds in a given year. If they get this wrong, or the strain mutates, a person can still get the flu, despite having had the flu jab.
