The CDC says that their monitoring programs have uncovered a very small increased risk for Guillain-Barre syndrome, Bell's palsy and thrombocytopenia among people who were injected with the H1N1 vaccine. But the increased risk is so small, the CDC says it can't tell if the apparent increase in danger is the result of a problem with the vaccine or simply the result of better monitoring. "Because the effects are so small, it is hard to say whether it is due to chance or a real effect," said Dr. Stephen Redd, director of the CDC's influenza coordination unit. Story
