PHILADELPHIA, July 31, 2012 /PRNewswire/ -- GlaxoSmithKline [NYSE: GSK] announced today it has begun shipping the first lots of 2012-2013 FluLaval® (Influenza virus vaccine) and Fluarix® (Influenza Virus Vaccine) to CDC distribution centers and U.S. healthcare providers. This follows approval of this season's GSK seasonal influenza vaccines by the U.S. Food and Drug Administration's Center for Biologics Evaluation and Research. FLULAVAL is approved for use in adults (18 years of age and older) to help protect against influenza disease caused by the virus subtypes A and B contained in the vaccine. FLUARIX is approved for use in adults and also children (3 years of age and older). "The three strains of influenza virus in the seasonal influenza vaccine can change from year-to-year based on estimates of the strains that will circulate in the upcoming season," said Dr. Leonard Friedland, VP and Head, Clinical/Medical Affairs, GSK North America Vaccine Development. "This is a key reason why the CDC recommends everyone six months of age and older gets an influenza vaccination every year. For the 2012-2013 influenza season, two of the three strains have been changed compared to last year's formulation." Beginning with today's initial shipments, GSK flu vaccine will be available to most healthcare providers in time to address back-to-school immunization needs of parents and children. Subsequently, the company anticipates being able to supply its seasonal flu vaccines to the US marketplace well into 2013.
