"The addition of a fourth influenza virus strain to the seasonal influenza vaccine formulation has the potential to make a substantial impact in reducing influenza disease and influenza-related complications, hospitalizations and deaths among those who contract the disease," said David Greenberg, M.D., Senior Director, U.S. Scientific and Medical Affairs, Sanofi Pasteur. "Two influenza B-lineage strains typically co-circulate in the U.S each year, so it makes sense to include both in the vaccine rather than attempting to predict which of the two will be the dominant strain. In fact, in six of the past 12 influenza seasons, the B strain selected by health authorities for inclusion in the vaccine was not the predominant B-lineage strain that circulated during the next influenza season."
