"Shots of vaccine are prepared for usage during a counter the H1N1 swine flu virus vaccination session for medical staff at the hospital in Chur, Switzerland, in this Nov. 2009 file photo. About 800,000 pre-filled syringes of swine flu shots intended for young children have been recalled because tests indicate the vaccine doses lost some strength, government health officials said Tuesday."

"Despite the nature of the recall, children who were vaccinated with the weakened doses should not be revaccinated because the antigen content "is only slightly below the 'specified' range," according to the CDC. In other words, even the weakened level of the vaccine is still expected to be protective."
