Vaccinating Children against Flu Helps Protect Wider Community
Results of a clinical trial conducted in a largely self-contained religious community during the 2008-09 influenza season show that immunizing children against seasonal influenza can significantly protect unvaccinated community members against influenza as well. The study was conducted to determine if immunized children could act as a barrier to limit the spread of influenza to the wider, unvaccinated community, a concept known as herd immunity.
