Study Summary

This is an observational, retrospective, cohort, safety study in pregnant women (vaccinated with Pertagen®) and have given birth in Thailand from January 2021 to April 2024 and infants born to pregnant women who received Pertagen®.

Following approval of the final protocol from the Institutional Review Board (IRB) and/or Ethics Committee (EC) and written approval from hospital directors/medical doctors as per requirements of each institutions. The assigned Ob-gyn specialist/physician at each study site will review the medical record of pregnant women (January 2020 to April 2024) based on study selection criteria. Safety information of pregnant women who received Pertagen® and have given birth from January 2021 to April 2024 and infants born to pregnant women who received Pertagen® will be obtained from medical records in hospitals/clinics and will be reported in case report form (CRF) by assigned Ob-gyn specialist/physician at each study site. The assigned Ob-gyn specialist/physician at each study site who will review the medical records and report the data in case report form (CRF) is not part of the research team.

Study Description

A CRF has been developed and will be used to collect safety information on pregnancy outcomes including the health status of infants at birth. The following definitions will be used for data collection

The 2nd trimester of pregnancy is defined as gestational period between 13-26 weeks
The 3rd trimester of pregnancy is defined as gestational period from 27 weeks to delivery.
Full term birth is defined as delivery of a baby at gestational age (GA) ≥37 weeks.
Preterm birth is defined as delivery of a baby at GA<37 weeks.
Complications during delivery may include postpartum hemorrhage, maternal fever or infection, or any maternal and fetal indications that may require emergency caesarean section.
Safety information of pregnancy and delivery outcome refers to health of women during pregnancy and childbirth (WHO 2024). The most common direct causes of maternal injury and death are excessive blood loss, infection, high blood pressure, unsafe abortion, and obstructed labor, as well as indirect causes such as anemia and heart disease (WHO 2024).
A newborn is defined as healthy at birth if discharged from the hospital in the first few days of life.
A newborn is defined as not healthy if with difficulty of breathing, congenital abnormality or other conditions that would require prolonged stay at the hospital.

To ensure the privacy and confidentiality of the collected data, strict adherence to all relevant data protection regulations will be followed.
