CDC urges H1N1 vaccination because pandemic's course remains unpredictable
TUESDAY, Dec. 1 (HealthDay News) -- A U.S. health official said Tuesday that H1N1 swine flu infections appear to be on the wane nationally, but many experts agreed the virus could return in force later this winter.

Right now, close to 70 million doses of vaccine are available, with more on the way, and most people should be able to get vaccinated this month, he said.
And there was one more piece of good news. Duke University Hospital in Durham, N.C., which last week reported four cases of very ill patients with H1N1 that did not respo
