Seasonal vaccine no help against swine flu
ATLANTA — U.S. health officials say they are "very pessimistic" that the seasonal flu vaccine protects against the unique swine flu infecting people in the United States, Mexico and other countries.

A U.S. Centers for Disease Control and Prevention official said Sunday afternoon that tests of the seasonal vaccine and the new virus show no cross-reaction, suggesting that people who got the vaccine have no added protection against the new bug.
