Flu Shot Connected To Miscarriage?

According to Business Insider, "In September 2017, a study found a link between miscarriage and getting a flu shot during the first trimester of pregnancy." Researchers have emphasized that this does not prove flu shots cause miscarriages and that it shouldn't dissuade women from getting a shot this flu season. Doctors urge pregnant women to get flu shots, because the influenza vaccine is an essential element of prenatal care."
