“…Mohammed et al, 10 found that there were 66.9% male respondents, 37.8% were diplomas, while 62.2% had a degree of work experience ranging from 4 months to 14 years Kumar et al, 11 in an observational cross-sectional study in Etawah found that all respondents were male and approximately one-third were post-graduate Kumar et al, 7 showed that among cold chain handlers of all the 29 PHCs, where In the present study, it was observed that the correct knowledge regarding internet-based eVIN, vaccine's placement in the freezer compartment of domestic refrigerator, keeping items other than vaccines in ILR or DF, the conditioning of icepacks, keeping vaccines away from walls in vaccine carriers, and correct place of thermometer in ILR/DF was correctly given by all of the CCHs, while knowledge about AEFI, its primary management, about a hold over time, and keeping dropper in ILR were given least correctly. Similar studies show that the overall level of good knowledge of vaccine handlers and good status of cold chain and vaccine management was in approximately half of the participants Gebretnsae et al, 12 Mohammed et al, 10 found that approximately half of vaccinators and vaccine handlers had satisfactory knowledge, positive attitude, and good practice, Kumar et al,11 in an observational and cross-sectional study in Etawah and found that all of the cold chain handlers interviewed had the knowledge of vaccine cold chain and most of them had knowledge of temperature range for vaccine storage. Among the 34 cold chain handlers the skills in the identification of light-sensitive vaccines, stages of VVM, checking of ice thickness, precautions of using a dropper, arranging vaccines to temperature sensitivity, labeling of open vials both multidose and open vial policy, condition of ice packs, proper disposal of vials, and preventing of vaccines from touching the walls were able to perform splendidly by all of the cold chain handlers while in tasks of using eVIN application, placing thermometer, reading of temperature, performing shake test, entry of temperature data into the logs, and preparing AEFI kit was only be able to perform by approximately a quarter of them.…”
