Because of increased risk of complications from influenza, vaccination of adults and children with asthma is recommended by the Advisory Committee on Immunization Practices. The Healthy People 2010 Objectives call for annual influenza vaccination of at least 60% of adults aged 18-64 years with asthma. However, Centers for Disease Control and Prevention (CDC) investigators have determined that the vaccination levels among asthma sufferers falls well short of this guideline. The results of their study are published in the August 2009 issue of the American Journal of Preventive Medicine.
