What this research studies

If you take part, the team will examine how antibodies from a pregnant person's pertussis vaccine move to the baby through the placenta and breast milk. They will measure antibody levels and test whether those antibodies prevent newborns from becoming colonized or passing Bordetella pertussis to others. The work combines lab tests and sample-based experiments to clarify whether maternal antibodies stop infection or only reduce disease symptoms. The goal is to understand risks and protections for babies too young to be fully vaccinated.

Who could benefit from this research

Good fit: Ideal participants would be pregnant people (especially in the 2nd or 3rd trimester) and their newborns in the first weeks of life who can provide health information and samples.

Not a fit: People outside the newborn period or those seeking immediate treatment for active whooping cough are unlikely to receive direct benefit from this research.

Why it matters

Potential benefit: Results could lead to clearer maternal vaccine guidance that better protects newborns from whooping cough.

How similar studies have performed: Prior studies show maternal antibodies can reduce severe pertussis in infants, but it remains unclear whether they prevent infection or transmission, so this work addresses that gap.
