Flu at epidemic level, 15 children have died

This year's flu outbreak has reached epidemic levels. At least 15 children have died so far and there's concern those numbers could rise.

Earlier this week, the CDC reported high flu activity in 22 states. With this year's vaccine less effective, flu related hospitalizations are up.

Health officials say people over the age of 65, children under five, pregnant women and those with medical conditions are at the greatest risk of getting the flu.
