Number of Outcomes From Pregnancies With Reported Exposure Within 28 Days of Last Menstrual Period Primary · From the date of registration until the date of documentation of pregnancy outcome (up to 10 months i.e. 28 days prior to conception till the month of estimated date of delivery)

Participants were followed from registration upon exposure to Twinrix within 28 days prior to conception until data on pregnancy outcome was obtained. Follow-up via telephone or a form mailed to the contact was sought in the month of the estimated date of delivery. Pregnancy outcomes were stratified by the trimester of exposure, with an additional stratum for preconception exposure with no subsequent administration during pregnancy; multiple exposures were classified by the earliest trimester of exposure. Gestational weeks were counted from the date of the last menstrual period. The second tr

Sponsor's own description

The purpose of the Twinrix Pregnancy Registry is to prospectively collect data describing exposure to Twinrix before or during pregnancy, potential confounding factors (such as exposure to other medications) and information related to the outcome of the pregnancy. This is a prospective, voluntary, observational, exposure-registration study. Twinrix is designated as Food and Drug Administration (FDA) Pregnancy Category C, which means that its safety in human pregnancy has not been determined. The Registry is intended to provide an early signal of potential risks in advance of results from formal epidemiologic studies. Registry statistics can supplement animal reproductive toxicology studies and assist clinicians in evaluating the potential risks and benefits of vaccination for individual patients.
