The Hartford HealthCare Medical Group is contacting patients who may have received vaccines that were not stored at the proper temperature.
Representatives said 5,003 doses were given to 3,833 patients throughout the Hartford HealthCare system. The affected vaccines were for a variety of illnesses, including influenza, pneumonia, and tetanus.
Temperature control problems were found at four of its locations in Enfield, West Hartford, Storrs, and Unionville starting on January 1, 2013.
Dr. Rocco Orlando, Hartford HealthCare's Chief Medical Officer, said the discovery was made during routine checks.
"We became aware that in our Enfield practice, we found that one of the refrigerators had malfunctioned and that as a result, we became concerned that some of the vaccine might not have been effective," Dr. Orlando said.
He added that they don't know of any patients being harmed, but they are encouraged to get re-vaccinated. Hartford HealthCare will provide these patients with new vaccinations at no charge.
