I'm Pregnant. Should I Get a Flu Shot?

I just found out that I'm 6 weeks pregnant. Do I need to get the flu vaccine or will it affect my pregnancy?

The Centers for Disease Control and Prevention (CDC) recommends the flu vaccine for all women who are pregnant — and for those who are considering pregnancy, who have recently given birth, or who are breastfeeding during flu season.

Pregnancy leads to changes in a woman's body. The immune system becomes a bit weaker. That makes it easier for pregnant women to catch whatever bug is going around. In addition, changes in how the heart and lungs work during pregnancy make it more likely that the flu will develop into a more serious problem, like pneumonia.

Studies have shown that the flu shot is safe during pregnancy. Although the flu vaccine has come in a nasal spray form in the past, the nasal spray is not recommended for pregnant women or the general public.

If you develop flu-like symptoms before or after you've been vaccinated, call your doctor right away. Pregnant women who catch the flu may need to take antiviral medicine to decrease the chances of developing complications.
