ATLANTA (AP) - 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. It's possible that people who have been exposed to flu viruses every year - especially older people, with a greater exposure history - may have some natural immunity, the CDC official said in a call with reporters.More like this story
