Progress in researches on logistic capacity allocation of immunization units under mass vaccination

During the mass vaccination, the involved immunization units should undertake some extra vaccination services besides routine vaccination and the immunization units may need to expand their logistic capacity. Published studies showed that the volume of refrigerators, the number of vaccination-related staff and the area of clinics are the key aspects of immunization logistic capacity. Focusing on the three aspects mentioned, we reviewed published researches on configuration standards and the demand measurement methods of immunization logistic capacity. Problems in logistic capacity allocation of the involved immunization units, potential impacts of these problems on mass vaccination, and countermeasures to deal with the problems were also discussed.
