BackgroundThe United States has experienced two shortages of heptavalent pneumococcal conjugate vaccine (PCV7). National guidelines called for deferring the third and fourth PCV7 doses from healthy children during these shortages. However, recommendations were not the same during the first and second shortages, and recommendations changed over time during each of the shortages as shortages worsened.ObjectivesTo measure PCV7 immunizing behavior for healthy children during shortage and non-shortage periods and assess the accuracy of the physicians’ reported immunizing behavior when compared to their actual immunizing behavior.MethodsWe reviewed medical records in 14 randomly selected practices to measure actual immunizing behavior during shortage and non-shortage periods. We surveyed pediatricians in the Greater Cincinnati area to ascertain reported immunizing behavior. Actual and reported immunizing behaviors were compared.Results2888 medical records were reviewed; surveys were obtained from 51 pediatricians (65% response rate). During periods of non-shortage, 74% of healthy children received their first two doses of PCV7 on time, whereas during periods of shortage, only 66% of healthy children received their first two doses of PCV7 on time. Compared with measured immunizing behavior from chart reviews, 54–76% of the pediatricians overestimated their compliance with guidelines to defer the fourth PCV7 dose while only 5–20% underestimated their compliance.ConclusionsPhysicians often overestimated the percentage of children whose vaccine doses they deferred during vaccine shortages. Despite these findings, physicians were able to maintain high coverage with the first two PCV7 doses among healthy children.
► We assessed physicians’ immunizing behavior during pneumococcal vaccine shortages.
► We compared physicians’ reported immunizing behavior with their measured behavior.
► Physicians often overestimated rates of deferring doses during vaccine shortages.
► Deferral rates were impacted by shortage severity.
