New Vaccine Surveillance Network (NVSN)
The New Vaccine Surveillance Network (NVSN) includes research sites that focus on population-based surveillance and data collection on the use and impact of new vaccines and the impact of vaccine policies. Since 2006, NVSN sites have conducted active, population-based surveillance for hospitalizations and outpatient visits associated with acute gastroenteritis (AGE) in children (2006-present). From 2000 to 2009, three NVSN sites conducted surveillance for acute respiratory illness (ARI).
NVSN sites also conduct special studies involving new vaccines and vaccine recommendations. Study topics include vaccine effectiveness, the cost-benefit of vaccine programs, coverage of new childhood vaccines, and feasibility studies of new vaccine implementation recommendations. NVSN sites are supported by a cooperative agreement with CDC.
