Influenza Vaccine Post-Introduction Evaluation (IPIE)

To support national immunization programme managers to optimize the introduction and implementation of influenza immunization programmes in countries, WHO has developed the Influenza Post Introduction Evaluation tool (IPIE). This tool is designed to provide a systematic method for evaluating a national influenza immunization program. It uses structured interviews at the national, provincial, and health facility levels and with specific target groups supplemented with systematic observations of vaccination sessions and vaccine storage sites.
