LEBANON, N.H. — A New Hampshire hospital is working to revaccinate hundreds of children after discovering that its vaccines were stored at inconsistent temperatures.

State public health officials have said the affected vaccines from Alice Peck Day Memorial Hospital in Lebanon aren’t harmful but might have lost some potency. That means they could provide less immunity to disease.

The problem occurred over the course of 14 months, from September 2014 to October 2015. The hospital offered to revaccinate 827 patients at no cost to them or their insurance companies.

APD Chief Executive Sue Mooney tells The Valley News that the revaccination program is off to a strong start.

Hospital spokesman Peter Glenshaw says about 250 patients have been revaccinated as of Feb. 8.
