Flu vaccine more effective this year; milder season so far
The flu vaccine is doing a better job this year.
Preliminary data suggest it is 59 percent effective. That's a big improvement from last winter's nasty flu season when the vaccine was less than 20 percent effective.
Unlike last year's vaccine, this year's is a good match to the strains making people sick.
It's been a milder flu season so far, though health officials said it has not yet peaked.
The numbers were presented Wednesday at a medical meeting in Atlanta.
