Never mind flying, steep roofs and shinnying down chimneys, some Santas are worried about catching swine flu from kids.

The president of a national volunteer Santa group wants Santas to be given priority for the swine flu vaccine, and not just because they're exposed to kids.

Research has suggested obesity could be a risk factor for severe swine flu. Ernest Berger of Santa America says about a third of the nation's Santas are at least 100 pounds overweight.

Berger has asked Alabama Congressman Jo Bonner to look into the idea. Meanwhile, Santas across the country are taking off their gloves, pulling out the hand sanitizer and taking other precautions to avoid spreading germs.
