Vaccine management practices among healthcare workers in Morogoro, Tanzania: a cross-sectional study.

Healthcare workers' vaccine and cold chain management knowledge were good for temperature data reading and documentation. However, the practices were poor for some health facilities. The gaps observed in this study inform health managers and policymakers toward establishing interventions to improve health workers' knowledge and practice, including mentorships, supervision, and training to guarantee that each child in all communities reaps the benefits of immunisation services.
