Vaccine Carrier is basically a insulated containers that, when lined with coolant packs, keep vaccines and diluents cold at the time of transportation. It is smaller than cold boxes and are easier to carry when walking. This can be used for transporting vaccines from health facilities with refrigeration to stretch sessions where refrigeration & ice are not available. It is mainly carried by a single health worker travelling on foot or by other means, where the combined journey time & immunization activity ranges from a few hours to a whole day.
