Influenza (flu) vaccination is recommended for all pregnant people at any stage of pregnancy to protect themselves and their babies.
There is good evidence to show the inactivated influenza (flu) vaccine is safe for pregnant people and their babies. Pregnant people, or those intending to become pregnant, should receive the inactivated influenza vaccine (given by injection), not the live attenuated influenza vaccine (given as a nasal spray).
Influenza can be very serious during pregnancy. Normal changes that happen in the body during pregnancy, like changes in the immune system, make pregnant people more likely to get really sick from influenza and to be hospitalized. Influenza can also be harmful to the baby.
