Thanks to changing state laws, the proportion of adults vaccinated in retail stores reached 18.4% during the 2010-2011 season, a jump from 7% in 2006-2007. As of 2009, all 50 states allow pharmacists to administer the flu vaccine; that's up from 22 states in 1999. "Patients trust their pharmacists and find them to be the most accessible providers of patient care," says Steven Anderson, CEO for the National Association of Chain Drug Stores. Report
