State health officials say rationing flu shots has worked so well that many providers have excess supplies.
They´re now worrying that some high-risk people may not get the shots they need — and that some shots may be wasted if they aren´t used in what so far has been a relatively mild flu season.
The situation is a reversal from the near panic this fall after half the nation´s vaccine supply was disrupted.
Pressure is now building for state and federal health officials to ease restrictions on who can get the shots.
Four states have already done so, and California is considering it as well.
The flu season usually peaks next month.
