B-lineage mismatch in the 2015-2016 flu season

Update from the Centers for Disease Control and Prevention


B Lineage Mismatch in the 2005-2006 Influenza Season

With coverage from both B lineages, a quadrivalent vaccine
can help reduce B-lineage mismatch and may help reduce the overall
burden of influenza8
