The COVID-19 emergency and vaccine introduction compelled countries to invest in new immunization information systems to collect, manage, and use COVID-19 vaccination data. The COVID-19 to routine immunization information system transferability assessment (CRIISTA) framework provides a systematic process for gathering evidence and making recommendations to inform these decisions. On May 24, 2023, MOMENTUM Routine Immunization Transformation and Equity project held a webinar presenting an overview of the CRIISTA framework, key users and use cases, and the recommended assessment process.
