In May 2004, the Advisory Committee on Immunization Practices recommended universal influenza vaccination for children aged 6 to 23 months.1 However, as shown by Humiston et al2 in a recent issue of the ARCHIVES and Daley et al,3 costs, lack of immunization clinics, and limits of recall systems are barriers to widespread vaccination, even for children with medical conditions that require influenza vaccination.
