Pregnant women are strongly recommended to receive influenza vaccine in each pregnancy.

Women who acquire influenza during pregnancy have an increased risk of morbidity and mortality.25 Women who acquire influenza in the later stages of pregnancy have a higher risk of: 

  • complications from influenza 
  • delivering a preterm baby32-41 

Vaccinating pregnant women also protects their infants from influenza in early infancy. This is due to transplacental transfer of high-titre influenza-specific antibodies.33,42,43 

Timing of influenza vaccination during pregnancy

Pregnant women can receive influenza vaccine during any stage of pregnancy. The timing of vaccination should be considered in relation to the influenza season and vaccine availability.

Women who are in their first trimester in the first quarter of the year may wish to wait until the current year’s seasonal influenza vaccine becomes available, rather than receiving the previous year’s influenza vaccine.

Influenza vaccine can safely be given at the same time as dTpa (reduced antigen content diphtheria-tetanus-acellular pertussis) vaccine.

Women who received the previous year’s seasonal influenza vaccine early in their pregnancy can receive the current seasonal influenza vaccine (when it becomes available) later in the same pregnancy. 

See Table. Vaccines that are routinely recommended in pregnancy: inactivated vaccines in Vaccination for women who are planning pregnancy, pregnant or breastfeeding for more details.
