**2. Materials and Methods**

This article spotlights examples of strategies used by five countries—Cambodia, Cameroon, Kenya, Nigeria, and Uganda—that have exhibited exemplar performance in strengthening routine immunization programs and that have restored lost coverage levels back to pre-pandemic levels to identify country-level learnings and inform and support other countries to adopt similar practices. No personal or patient-level health information was gathered for this work, and this work is not considered human subjects research. Coverage data was obtained from WHO-UNICEF and reported at the country-level.
