"Conclusion The objective of this study was to document the number of vaccine shortages over time in the period 2004–13 and quantify the relationship between prices and shortages during this period. The results should inform policy makers and administrators of the trade-offs between saving money and averting shortages. Government payers should carefully consider the benefits of averting vaccine shortages when evaluating prices for vaccines, including older vaccines whose prices have been subject to caps. "
