Here is some additional information from the local newspaper:
Dr. Alan Peterson, the director of environmental and community medicine at Lancaster General Health…says pregnancy changes the immune system, and a case of the flu can pose a severe threat to mother and unborn child. That’s why organizations such as the U.S. Centers for Disease Control and Prevention and the American Academy of Obstetricians and Gynecologists recommend flu shots for most pregnant women.
Breton says she explained her flu shot reservations to her employer, and also provided a doctor’s note which described her history of miscarriage. The doctor wrote, “In my view getting the flu shot would significantly and negatively impact her health because of the increased fear and anxiety it would create as well as the emotional impact it could cause if she does miscarry again.”
Carolyn Carlson, a registered nurse and the president of Horizon, said in an email that requests for exemptions are reviewed by a committee of doctors.
A couple other important mentions:
Lancaster General Health (Dr Peterson’s hospital) is one of several area hospitals which co-own Horizon Healthcare Services (the company which fired Dreonna Breton)
Sanofi Pasteur, the maker of the vaccine in question, stated that results of clinical studies involving pregnant women weren’™t included in the research presented decades ago when flu vaccine received government approval. That is why the package insert had the caution which caused Breton to become concerned.
