Immunization, Vaccines and Biologicals

Monitoring and surveillance


Our focus is to monitor and assess the impact of strategies and activities for reducing morbidity and mortality of vaccine-preventable diseases. Collection, analysis and interpretation of surveillance data is vital to guide vaccination policies and programmes and ensure immunization targets are being reached.

Our core activities consist of the disease surveillance and burden, monitoring of immunization systems and reporting of data and statistics and are guided by the principles set out in the (Global Vaccine Action Plan)

Surveillance and burden


Information on the current burden of vaccine preventable diseases, including disease-specific estimates of morbidity and mortality and global laboratory surveillance networks.

Monitoring and Assessing Immunization Systems


Information on monitoring the performance, quality and safety of immunization systems through indicators, including immunization coverage.

Data and Statistics


Reports from WHO Member States including information on estimates of national immunization coverage, reported cases of vaccine-preventable diseases, immunization schedules, and indicators of immunization system performance.
