VoICE Immunization Evidence
Influenza in infants born to women vaccinated during pregnancy
Maternal immunization offers an opportunity to protect the mother and fetus, but also passes this protection on to the infant after birth.
Key Evidence: Infants born to mothers who reported receiving influenza vaccination during pregnancy had a 64% lower risk of getting influenza-like illness in their first 6 months of life, a 70% lower risk of laboratory-confirmed influenza, and an 81% lower chance of being hospitalized with influenza than infants whose mothers did not report getting the influenza vaccine during pregnancy. Since influenza vaccines are not effective in children less than 6 months old, immunizing pregnant women against influenza is a public health priority.
