A systematic method for evaluating the potential viability of local vaccine producers

Vaccine production exists in > 55 countries, but many production facilities cannot assure a reliable supply of existing or new vaccines. By analysing the characteristics of successful producers, we have identified seven critical elements for viability, each defined by several indicators. Each indicated weakness implies an investment to correct it. Thirty-one manufacturers were assessed based on these viability indicators and the implied investment costs. Three general groupings were found. 'Viable' producers scored well in all seven categories. Those with a 'low probability' of viability are weak in all areas. Facilities regarded as 'potentially viable' may produce sufficient vaccine to meet national needs, but must develop appropriate structures to effectively manage change. This analysis provides a logical system for governments and donors to evaluate the potential effectiveness of further investment in local vaccine production.
