H1N1 Vaccine Maker Recalls 800,000 Doses
Nearly a million doses of H1N1 vaccine for infants and toddlers (ages 6 months – 3 years) were recalled on Tuesday. The vaccine reportedly lost strength since its distribution throughout the country last month. The vaccine was strong when the shots were originally shipped, according to the manufacturer, Sanofi Pasteur; however, tests done weeks later revealed the potency had fallen about 12 percent below the government standard.
By now, most of the shipment has already been used, but doctors are asked to return any unused doses.
Officials with the U.S. Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC) and Sanofi Pasteur say the strength of the vaccine is still high enough to protect children who received it. Parents can rest assured that already injected vaccine dosages are safe and effective, according to Dr. Anne Schuchat, a CDC flu expert.
