"When staff members at a Wellesley, Mass., school went to the nurse last Friday, they expected to be injected with a vaccine for theH1N1 flu. What they received instead was a shot of insulin resulting in a bout with low blood sugar. Share Seasonal shots may "prime" the immune system to react to the H1N1 virus. While the staffers seem to be suffering no long-term damage from mistakenly receiving the insulin injections, investigations are ongoing to determine what caused the medical error. Indications thus far have been that a school nurse was responsible. The nurse has been temporarily relieved of duty. While ABC News contacted people at the departments of health for the town of Wellesley and the Commonwealth of Massachusetts, as well as the Wellesley School District, it remains unclear how the flu vaccine, which is distributed in pre-filled syringes, was mistaken for insulin, which is drawn from a vial because each dose needs to be calibrated when it is given. Such errors have happened before. This past fall, a number of people in the neighboring town of Needham received a seasonal flu vaccine in place of the H1N1 vaccines they were supposed to receive. And in 2007, a teacher in the nearby town of Attleboro also received an injection of insulin instead of the intended flu shot. "

"PositiveID (PSID) is to begin a study of its Health Link implantable microchip in diabetic, hypertensive and obese patients. The study -like everything else associated with the company formerly known as VeriChip - is bound to be controversial. The Health Link chip is implanted under a patient's skin. It can be scanned to access the patient's online medical records. The company's critics fear the chip will one day become mandatory, leading to a complete loss of medical privacy, or that Americans will be unable to receive healthcare unless they get chipped. BNET has noted that PositiveID also owns a credit monitoring and identity-theft prevention company, Steel Vault, and that it envisions its chips being linked to Google (GOOG), Microsoft (MSFT) and employers. PositiveID linked credit monitoring and the Health Link chip in its most recent 10-Q. While PositiveID's press release gives few specifics, it indicates that the study will have something to do with the Health Link chip and customers of HealthScreenDirect, a company that offers screening for diabetes and high cholesterol. Its says the study will be: … a prospective, randomized, comparative clinical study that will seek to address improving disease management through the use of appropriate, concise, and up-to-date patient health information available to both practitioners caring for diabetic, hypertensive and obese patients and the patients themselves through the utilization of PositiveID's personal health record (Health Link) and an electronic medical records system. PositiveID CEO Scott R. Silverman said in the statement that the study will also advance the company's in-development glucose-sensing chip. Silverman is doubtless hoping that patients with the chip - and with their health records online - will have better outcomes in terms of managing their diabetes than those doing it the old-fashioned way. The unanswered question is why health record access - or even a microchip
