Pregnant Women & Influenza (Flu)
Flu is more likely to cause severe illness in pregnant women than in women who are not pregnant. Changes in the immune system, heart, and lungs during pregnancy make pregnant women more prone to severe illness from flu as well as hospitalizations and even death. Pregnant woman with flu also have a greater chance for serious problems for their unborn baby, including premature labor and delivery.
Flu shots will protect pregnant women, their unborn babies and even protect the baby after birth.
The Flu Shot is the Best Protection Against Flu

The flu shot given during pregnancy has been shown to protect both the mother and her baby (up to 6 months old) from flu. (The nasal spray vaccine should not be given to women who are pregnant.)

Flu shots have not been shown to cause harm to pregnant women or their babies. It is very important for pregnant women to get the flu shot.
