A nurse administering flu shots to dozens of employees of a pharmaceutical company reused syringes, the state Department of Health said Wednesday. There is a low risk of infection and syringes that hold the vaccine, not needles, were reused, they said. But state and local health officials, as well as the federal Centers for Disease Control and Prevention, are recommending testing for hepatitis B and C and HIV, which can spread via blood. Officials said it happened Sept. 30 when a nurse with TotalWellness administered flu vaccines to 67 employees of Otsuka Pharmaceutical in West Windsor.
