Half of parents in the United States would consent to have their children receive the flu vaccine in school, according to a survey from the Brown School at Washington University in St. Louis. It was among the first to provide national data on parent preferences on school-administered flu shots. “This study shows the potential to use schools for large-scale influenza vaccination programs in the U.S.,” wrote the study’s lead author, Dr. Derek S. Brown, assistant professor at the Brown School.
