Story Summary: The ongoing NIAID-sponsored trial began in mid-August at five sites nationwide. The preliminary results are based on blood samples taken eight to 10 days after the first vaccination. Immune responses were strongest among the oldest children, those 10 to 17 years old. In this group of 25 children, a strong immune response was seen in 76 percent who received one 15-microgram dose of vaccine. These results are not unexpected and are both similar to what is seen with seasonal influenza vaccines and consistent with what we and our colleagues at the Food and Drug Administration anticipated, notes Dr. Fauci. It is anticipated that the immune response to the 2009 H1N1 influenza vaccine will be similar to that of seasonal influenza vaccination and will continue to rise for several weeks following vaccination, says Dr. Fauci. The vaccine being tested in this trial is manufactured by Sanofi Pasteur in Swiftwater, Pa. , in the same manner as its licensed seasonal vaccine, which is used every year in millions of children, and is the same formulation recently licensed by the FDA to protect against 2009 H1N1 influenza.

Like inactivated seasonal influenza vaccines, the vaccine contains a purified part of a killed virus and cannot cause flu.
