Some of the antibiotics that are used in flu shots are not safe during pregnancy, why is the flu shot still ok in early pregnancy?

Flu shot: Yes, it's safe to get a flu shot during pregnancy. In fact, the Centers for Disease Control and Prevention and the American College of Obstetricians and Gynecologists recommend that all women who are pregnant during flu season get a flu shot, regardless of their trimester.

Life is that way: There is risk and benefit to everything we do, and to everything we do not do. Pregnancy has its dangers, many thousands of times higher than the risk of traces of antibiotics from vaccine manufacturing. For every 5000 births in the US, 1 of those mothers dies. In the US last year, about 35,000 people died from the flu. That's why pregnant women get flu shots, to save themselves and their babies.
