On Jun. 5, 2012, the U.S. Department of Health and Human Services (HHS) Office of the Inspector General (OIG) released a report titled “Vaccines for Children (VFC) Program: Vulnerabilities in Vaccine Management.”

The report identified multiple vulnerabilities in the distribution of vaccines for children (VFC) in the U.S. Key findings include that 76% of providers had exposed VFCs to inappropriate temperatures for at least 5 cumulative hours in a 2-week period. All 45 providers had recorded temperatures that differed from independently measured temperatures during the 2-week period.
