SP 1: Immunization Programs for Primary Health Care

Vaccine safety

What Does this Indicator Measure?

This indicator displays the proportion of countries using WHO’s global database VigiBase to report at least one serious adverse event following immunization (AEFI) per 1 million population, a marker that demonstrates a commitment to collecting robust, quality safety data to support policy making at all levels. Sharing AEFI data between all stakeholders within countries is critical to ensure that timely safety signals support an appropriate response at the country level. Further, pooling such reports into a global database can provide insights into trends and regional characteristics of very rare but significant AEFI that may be difficult to detect through national aggregate data.

How Will Progress be Measured?

Over the decade, immunization stakeholders committed to safety and transparency expect to see increasing numbers of countries using VigiBase to document detailed, individual case reports on serious AEFI. At present, 51 countries are adequately reporting through VigiBase.

Summary Table

Proportion of countries51 out of 194
Definition: Countries with documented individual serious AEFI cases safety reports per million total population.
Measurement approach: Individual serious AEFI reporting rate in million total population per year=Number of individually documented serious AEFI cases reported from country/sub-national area per year/Total population in the same country/sub-national area per year*1,000,000.

Annual number of individual AEFI case safety reports available in the WHO global database for safety monitoring.

Threshold: All countries with at least 1 AEFI individual case safety report/1,000,000 population.
