Vaccine safety and immune response study in pregnant women
Part of Infections clinical trials.
This study tests a vaccine that protects against three diseases—diphtheria, tetanus, and whooping cough—given during pregnancy. Researchers want to see if the vaccine is safe for pregnant women and their babies, and whether it helps protect newborns.
Summary written for real people, not researchers, by Clin2.

This trial tests a reduced-dose vaccine that protects against diphtheria, tetanus, and whooping cough (pertussis). It is designed for people 6 years and older who have not recently received other vaccines and are generally healthy.
This study tests when during pregnancy it is best to get the Tdap (whooping cough) vaccine. It aims to protect both mother and baby from whooping cough in the first months after birth.
This trial tests a new vaccine that protects against diphtheria, tetanus, and pertussis (whooping cough). It is for healthy infants who are about 2 months old and live permanently in the area. The goal is to see if the vaccine is safe and works well.
This trial tests a new combination vaccine that protects against whooping cough, diphtheria, and tetanus for people aged 10 and older. It aims to see if the vaccine is safe and helps the body build immunity.
This trial tests different ways to help partners of pregnant people get the Tdap vaccine (a shot that protects against tetanus, diphtheria, and whooping cough). The goal is to find the best way to increase vaccination rates among partners, which can help protect the newborn from whooping cough.
