HARTFORD, Conn. (AP) - State health officials have released data showing double-digit percentages of students in some Connecticut schools are exempted from certain vaccinations for religious or medical reasons. 

But the data contain some errors. 

Redding Superintendent of Schools Tom McMorran says wrong information was mistakenly submitted to the state for the Redding Elementary School, where he says only 4.7% of students are currently exempted from vaccinations for religious reasons.  The database listed 38%. McMorran sent an email to parents Friday letting them know the number was erroneous. 

The Department of Public Health posted the town-by-town, school-by-school information for the first time Friday on its website.  The U.S. is currently experiencing the largest outbreak of measles in 25 years. 

Connecticut has had three confirmed cases of measles this year. 

Up until Friday, the state provided only statewide immunization rates. Currently, 96.5% of the state’s kindergarten students are immunized for measles, mumps and rubella.
