The study is currently implementing a parallel–cluster randomized trial across Vihiga, Homa Bay, and Kiambu counties—randomizing sub-counties into intervention and control arms across 470 health facilities—to evaluate whether switching from 10-dose to 5-dose MR vials (with 35,000 five-dose vials supplied by the National Vaccines and Immunization Program and accompanying healthcare-worker training) can improve vaccine coverage and reduce wastage, assess acceptability by healthcare workers, examine supply-chain operational factors, and lower the total cost per vaccinated child. It is collecting administrative and wastage data; conducting key-informant interviews, focus groups, and cold-chain assessments; and intends to analyze these using segmented time-series and regression models. It aims to provide local evidence to the Ministry of Health on the viability of switching from 10-dose to 5-dose measles-rubella vials.
