Flu shots may not be the most pleasant experience in life, but you should feel good about taking care of your health and protecting the people around you during flu season. The last thing you want to worry about is whether the person administering the shot will do his or her job correctly.

Imagine a nurse injecting you with the wrong substance. That’s what apparently happened at an elementary school in Parkway, MO recently, according to the St. Louis Post-Dispatch.

Four teachers are believed to have been given insulin shots instead of flu vaccines. Two of the victims required emergency hospitalization for dangerous cases of “insulin shock.”

The Parkway school district offered flu vaccines to its employees. Teachers at Shenandoah Valley Elementary School received shots from the school nurse, whose office contains insulin for students.

One teacher suffered from convulsions before passing out, while another endured a severe bout of nausea and dizziness before also losing consciousness.

Hospital workers spent five hours returning their blood-sugar levels to normal, and the patients spent about eight hours in medical care.

While the nurse’s error appears to have been an honest mistake, the incident sheds light on the importance of both workplace safety and medical malpractice issues.

If you ever experience dangerous mistreatment from healthcare providers or an unsafe workplace, call your St. Louis personal injury attorneys for help sorting out the aftermath.
