(AP) — Wellesley school officials said several staff members at an elementary school had to be taken to the hospital after being injected with insulin rather than the swine flu vaccine. Superintendent Bella Wong said no students were ever in danger at Friday's vaccine clinic for staff at Schofield Elementary School and all the people who got the wrong shot have recovered.

Wong, in a letter to staff and parents Monday, said the insulin belonged to students with diabetes and was provided by their parents.

Wong said in the letter that the school nurse who administered the insulin to staff has been placed on paid administrative leave pending an investigation. She did not give the nurse's name.
