title: Recent changes in influenza epidemiology and vaccination recommendations.
abstract: Influenza disease continues to cause thousands of deaths in the United States. Due to the burden of influenza hospitalizations among children, inactivated influenza vaccine is now routinely recommended for children age 6-23 months. A live, attenuated influenza vaccine was licensed in 2003 for healthy persons age 5-49 years.
