LEBANON, N.H. (AP) — Alice Peck Day Memorial Hospital in Lebanon is asking more than 800 children to get revaccinated after discovering that vaccines were stored at inconsistent temperatures.
State public health officials say the affected vaccines are not harmful but may have lost some potency, meaning they could provide less immunity to disease. The problem occurred over the course of 14 months from September 2014 to October 2015, and the hospital is offering to revaccinate 827 patients at no cost to them or their insurance companies.
Dr. Benjamin Chan, the state epidemiologist, said he is pleased with the hospital’s response and is confident it is safely managing refrigeration of its vaccines.
There have been no instances of patients coming down with a vaccine preventable disease after receiving the affected immunizations.
