Are You Prepared for This Year's Flu Season?

摘要

The 2011-2012 US seasonal influenza vaccine virus strains are identical to those contained in the 2010-2011 vaccine. These include A/California/7/2009 (HlNl)-like (Figure), A/Perth/16/2009 (H3N2)-like, and B/Brisbane/60/2008-like antigens. Although the strains remain unchanged from the previous season, annual vaccination is still advised for those who received the vaccine last year.1
