摘要

The federal Centers for Disease Control (CDC) has updated its seasonal influenza Web center for the 2012-2013 flu season and recommends that employers begin promoting flu shots to employees as soon as the vaccines are available in their area. The 2012-2013 influenza vaccine is made from the following three viruses: 1. An A/California/7/2009 (HlNl)pdmO9-like virus; 2. An A/Victoria/361/2011 (H3N2)-like virus; and 3. A B/Wisconsin/l/2010-like virus (from the B/Yamagata lineage of viruses).
