<div class="title">Georgia lags in flu vaccination rates</div>
<div class="subtitle">Georgia brought down the national flu vaccination rate during the 2012-2103 season.</div>

May, 2013 cumulative flu vaccination rate for the 2012-2013 flu season. Vaccination coverage estimates by State National Immunization Survey (NIS) and Behavioral Risk Factor Surveillance System (BRFSS), 2012–13 influenza season.
