More than 900 patients are being advised to get a second vaccination because the one that they previously received may have been less effective due to fluctuating temperatures.
Hartford Healthcare said about one percent of vaccines and tuberculosis tests provided at several Hartford HealthCare Medical Group offices were ineffective. In total, Hartford Healthcare said 953 patients received 975 doses of vaccines.
These patients received vaccinations for flu, tetanus/diphtheria/pertussis, pneumococcal, hepatitis B, and meningococcal at the Plainville, Vernon, Colchester, Norwichtown, and Duncaster locations. They also could had tuberculosis testing was done at the Montville, Wallingford and Meriden sites.

Hartford Healthcare said they are "contacting the patients affected directly." If they can't get a hold of the person, they're also sending a letter. Anyone who needs to make an appointment is advised to call 877-707-4442.
The second round of vaccines will be free of charge, Hartford Healthcare said.
