COVID-19 vaccine post-introduction evaluation (‎cPIE)‎

Following new vaccine introduction into a routine immunization programme, the purpose of a post-introduction vaccine evaluation (PIE) is to evaluate the impact of the vaccine introduction on the country’s immunization programme and to rapidly identify problems needing correction as vaccination expands in country. The evaluation can not only lead to improvements in the implementation of the new vaccine and overall immunization programme but can also provide valuable lessons for other countries for future vaccine introductions.
