Morbidity and mortality resulting from influenza have remained high in the United States despite efforts to vaccinate high-risk populations, leading public health officials to expand their vaccination recommendations to include schoolchildren. Vaccinating schoolchildren against influenza is important not only because they are at high risk for becoming ill from influenza, but also because they spread the virus to each other and to those at risk in the community, including older adults. Annual vaccination has been recommended for all ages since 2010, and the Healthy People 2020 goal is the vaccination of 70 percent of children aged 6 months through 17 years. However, in the 2010–2011 season, only 47 percent of children in this age group received vaccine against influenza. Historically most children have received the vaccine from their primary care provider, but this is often inconvenient since primary care providers’ offices are normally open when children are at school and their parents are at work. This inconvenience may play a large role in the failure of the current clinic-based approach.
