mSphere of Influence: Pertussis Vaccination and Antibodies in Mothers and Infants.

Susana Portillo works in the field of mother-infant immunity with an emphasis on vaccination and prevention of respiratory diseases. In this mSphere of Influence, she reflects here on how two pertussis vaccine articles made an impact on her research. She discusses how much more remains to be understood about the role of maternal antibodies in preventing or reducing infant illnesses, their capacity to engage other immune components to deliver an efficient antimicrobial response, and their influence on the infant's own response to vaccination. She emphasizes the need for safe and effective interventions that strengthen maternal and infant immunity before and after birth.
