Official title
Clinical Study of Tetanus Toxoid, Reduced Diphtheria Toxoid, and Acellular Pertussis Vaccine (Tdap) Safety in Pregnant Women
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this observational study is to evaluate the safety of Tetanus Toxoid Reduced Diphtheria, Toxoid, and Acelluar Pertussis Vaccine (Tdap) in pregnant women at ≥ 20 weeks 0 days gestation receiving Tdap as part of standard practice. Prior Tdap/Td/TT history will be verified by medical record review when possible. There will be an emphasis on enrolling women who have received Tdap before the current pregnancy, to the greatest extent possible. Non-pregnant women who are receiving their initial Tdap will also be recruited. Injection-site (local) and systemic reaction data will be assessed on the vaccination day and during the 7 days following vaccination using either identical web-based or paper diaries, depending on the preference of the study participant. Pregnant women will be followed until delivery with comprehensive obstetric and neonatal outcomes obtained from review of the electronic medical record.
