A pregnant nurse was fired from her job after she refused to get a flu shot for fear of miscarrying.

Lancaster nurse Dreonna Breton was fired from her job after failing to comply with the company's policy that all employees are required to get a flu shot.

This year was the first time flu shots were mandatory at Horizons Healthcare Services in Lancaster, Pennsylvania where Breton, 29, worked as a nurse. She was told that all employees were now required to get the shot.

Breton told news reporters, "Any pharmaceutical has side effects, so I did research because I wanted to know exactly what it was that I was putting into my body."

She told her employers that she would not get the vaccine after she explained that there were very limited studies of the effects on pregnant women and had two failed miscarriages that year. After carefully researching the vaccine she said she "struggled to find the science behind mandated flu vaccinations."

"I'm not gonna be the one percent of people that has a problem," Breton told CNN.

Breton said she explained her flu shot objection to her employer, and also provided a doctor's note, which explained 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."

Some health care organizations allow employees who do not receive a flu shot to wear a mask; but Bretons offer to wear a mask during work did not sway her employers.

"I would say she has a million times greater chance of having a problem if she gets the disease rather than the vaccine," said Dr. Alan Peterson, the director of environmental and community medicine at Lancaster General Health.

The president of Horizon and a registered nurse, Carolyn Carlson, stated in an email that a committee of doctors reviewed requests for exemptions.

She wrote that flu vaccination is a condition of employment because it "protects our patients, employees, and community from getting this potentially serious infection."

Breton told CNN, "I know that the CDC says to get it, and that's fine, but it was our choice to avoid the flu vaccine and the unknowns that come with that."

Breton has no interest in taking legal action, she said. She stated she only wants the company to reevaluate their policy on vaccines for pregnant employees and she wished to continue working as a nurse.

"It would be a false statement to say the flu vaccine is known to be safe during pregnancy. I have lost my job, one that I love and am good at, because I chose to do what I believe is best for my baby," said Breton.
