Groups/Cohorts Assigned Interventions
Case Group
Subjects in this group are incident cases (i.e. newly diagnosed subjects) reported as having occurred in the previous twelve months before the recruitment consultation.
Biological: Cervarix
3 doses over a period of 6 months (Month 0 and ideally Month 1 and Month 6, with 1 month minimum between any two doses).
Other: Data collection
PGRx information system
Control Group
Subjects selected from the pool of potential referents reported by physicians in general practice, who meet the same general inclusion and exclusion criteria as the cases.
Biological: Cervarix
3 doses over a period of 6 months (Month 0 and ideally Month 1 and Month 6, with 1 month minimum between any two doses).
Other: Data collection
PGRx information system

Detailed Description:

PGRx is an information system that intends to bridge the resource gap to assess the effect of a drug on the risk of adverse events that are infrequent and/or with a long delay of onset. It uses some characteristics of the ad hoc case-control or case-referent design, transposed on a prospective, on-going, population-based recruitment plan. This particular design is called here systematic case-referent design in contrast to the ad hoc case-control or case-referent methodology. The PGRx information system is based on the routine and targeted recruitment of cases of a series of pathologies, compared to population-based referents for the study of exposure to a wide variety of drugs. Drug exposure ascertainment is obtained from two different sources in the PGRx.

system: A) A structured patient interview (telephone-administered questionnaire) B) The medical data form with the computerized medical prescriptions (interview guide)
