Ministers have announced that children aged between six months and five years will be the next group inoculated against the virus, which has killed more than 280 people in Britain.

Children's swine flu shots recalled over their potency Hundreds of thousands of children's swine flu shots manufactured by the French drug company Sanofi Pasteur have been recalled because tests indicate that the vaccine doses lost some strength, U.S. government health officials said Tuesday.
The recall, which is voluntary, is for about 800,000 prefilled syringes intended for young children aged 6 months to nearly 3 years. The shots were distributed across the United States last month, and most have already been used, the Centers for Disease Control and Prevention said. International Health Tribune, December 16, 2008
