Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will assess the risk of spontaneous abortion during weeks 1-23 and weeks 1-19 of gestation, respectively, and other pregnancy outcomes, in an exposed cohort, i.e. women with last menstrual period (LMP) between 30 days before and 45 days after, or 30 days before and 90 days after any dose of Cervarix, when compared to a non-exposed cohort, i.e. women with LMP between 120 days and 18 months after the last Cervarix dose. The data collected in the Clinical Practice Research Datalink General Practitioner OnLine Database (CPRD GOLD) in the UK, will be analysed in this study.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Convenience sampling will be used in this study. It is planned to include all eligible pregnant women (included in CPRD GOLD and who fulfil to the inclusion/exclusion criteria) in each of the two cohorts.
