Are influenza vaccines safe for pregnant people?
The inactivated influenza vaccine is considered safe at any stage of pregnancy. Pregnant people, or those intending to become pregnant, should receive the inactivated influenza vaccine, which contains killed influenza viruses that cannot cause infection.
People in the second half of pregnancy are at higher risk of influenza-related complications and at higher risk of hospitalization from these complications, especially those in the third trimester. As well, people at any stage of pregnancy who have chronic medical conditions are also at higher risk of serious influenza complications and should be vaccinated.
