Monitoring and Surveillance
This web page provides information about work being done to improve immunization monitoring and surveillance data in order to provide decision-makers with critical information both before vaccine introduction, as related to the existing disease burden and justification for introduction, and after vaccine introduction to monitor vaccine impact on disease and to assess vaccine safety. The page includes links to archived issues of two surveillance bulletins: the Global Invasive Bacterial Vaccine Preventable Diseases Information and Suveillance Bulletin; and the Global Rotavirus Information and Surveillance Bulletin.
