maternal vaccination

Maternal vaccination involves a pregnant woman receiving a vaccine to protect herself and her baby from certain infections. When vaccinated, she develops antibodies—proteins that help fight specific diseases—which can pass through the placenta to the developing fetus. This transfer provides the newborn with some immunity during their early months, before they can be vaccinated themselves. Maternal vaccination helps reduce the risk of serious illness for both mother and baby, especially for diseases like influenza, Tdap (whooping cough), and COVID-19. It is a safe and effective way to promote health during pregnancy.
