ABSTRACT

The aim of this study was to assess the knowledge and practices of health workers dealing with immunization services about the appropriate management of cold chain system. Their knowledge and practices concerning the surveillance activities of adverse events following immunizations [AEFIs] were also evaluated. A cross sectional study was conducted in all health offices providing immunization services in Alexandria. The required data were collected through an observational checklist and two interviewing questionnaires. This study concluded that the knowledge of health workers regarding immunization and cold chain is still low. The knowledge and practices regarding AEFIs is also poor. Extensive health education and training are needed to ensure that everyone involved in cold chain is familiar with all its facets. The study recommended provision with equipments, such as electric generators, solar refrigerators and cold chain monitors, which are considered important components for the safe storage of vaccine and successful immunization program
