(AP) -- U.S. health officials say there's no evidence that the swine flu vaccine is causing any serious side effects.
They say the vast majority of reports have been for minor things like soreness, redness or swelling where the shot was given. From early October through mid-November, about 22 million people were vaccinated.
Officials have been watching whether the new vaccine would cause a rare paralyzing condition called Guillain-Barre syndrome. That condition was seen in higher numbers than usual during a swine flu vaccination campaign in 1976. But there have been only 10 such reports so far in those who got the new swine flu vaccine.
The Centers for Disease Control and Prevention released the vaccine safety report on Wednesday.
