Additional key concepts from this publication:

Maternal immunization offers an opportunity to protect the mother and fetus, but also passes this protection on to the infant after birth.

Key Evidence: Vaccinating women during their second or third trimester of pregnancy with the Tdap vaccine was 81% effective in preventing pertussis in their infants in the first two months of life, according to a case-control study in Argentina.

From the VoICE Editors: This is one of the first studies to measure the effectiveness of maternal pertussis vaccination in a middle-income country and its findings support Argentina’s decision to introduce the vaccine.
