At least five children were given the wrong immunizations at a health clinic for the uninsured, including a 2-year-old boy who got an "excessive dose" of a cervical cancer prevention vaccine, authorities said. The Salem County-run "Shots for Tots" program has been shuttered while officials try to determine how and why the errors occurred. Two full-time nurses who ran the clinic have resigned from the county Health Department, and the county prosecutor's office is reviewing the matter. None of the children has apparently suffered any adverse health effects because of the errors. But the county has agreed to pay for the children's medical monitoring costs "for the foreseeable future."
