A week later, on November 16, Moderna announced that their own Covid-19 vaccine had been 94.5% effective in clinical trials. It is difficult to state whether this planned expansion will be sufficient for Covid-19 vaccines since we do not yet know the volume of each dose of a Covid-19 vaccine. It is imperative that each of these nodes are equipped with the appropriate cold-equipment to ensure proper vaccine storage and efficacy. This calls for a very rapid expansion of the vaccine storage capacity at all the nodes (central, district, upazila). Since vaccines need to be maintained within a range of temperature, ideally, they are transported in specialized refrigerated vehicles.
