Overview

NVSN was established to evaluate the impact of new vaccines and vaccine policies through active sentinel surveillance at three U.S. medical centers. The three charter sentinel sites are:

  • University of Rochester (Rochester, NY)
  • Vanderbilt University (Nashville, TN)
  • Cincinnati Children's Hospital Medical Center (Cincinnati, OH)

In 2009, NVSN was expanded to include the following sentinel sites:

  • Texas Children's Hospital (Houston, TX)
  • Seattle Children's Hospital (Seattle, WA)
  • Children's Mercy Hospital and Clinics (Kansas City, MO)
  • Children's Hospital and Research Center (Oakland, CA)

Together, the seven-site surveillance network is known as NVSN-Extended System (NVSN-ES).

As new vaccines are developed, licensed and made available for use, surveillance and monitoring are critical to address their impact on communities and populations. NVSN supports broad-based surveillance and research projects for acute gastroenteritis in areas with a population base of at least 500,000.
