Boostrix® Pregnancy Registry

for Boostrix® Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine, Adsorbed

This is a Pregnancy Registry for Boostrix vaccine (GSK) approved and marketed in the United States. GSK is collaborating with OTIS/ MotherToBaby Research Center for the Boostrix Pregnancy Registry. The Registry relies on voluntary reporting of pregnancy and exposures by women and health care providers (HCPs) who contact OTIS/MotherToBaby Pregnancy Studies, or the MotherToBaby network. The Registry is a research program and helps us gain further knowledge on Boostrix use during pregnancy.

To participate in this registry: enrolment in the registry is open to pregnant women living in the US and should take place before the outcome of pregnancy is known.
The study is observational: participants are never asked to take or change any aspect of their current health routine.
Participants complete 1-3 phone interviews during pregnancy and 1 interview after delivery. People are also asked to release the medical records for their pregnancy and for their baby. These records are used to capture information about a person’s health as the pregnancy progresses and the health of their baby after delivery.
