Brief Summary

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

In France, the vaccination coverage observed for HPV vaccination is low for a full-scale regimen, and has been falling since 2010. A high rate of HPV vaccination coverage has a significant epidemiological impact with a reduction in cervical cancer mortality.

There is less data on vaccinated catch-up patients. In 2017, these patients are 25 years of age or older and carry out screening smears.

The aim of this study is to demonstrate whether HPV catch-up vaccination results in a decrease in the abnormal smear rate compared to the rate in unvaccinated patients.

If so, these data will help mobilize doctors to vaccinate patients against HPV, even in catching-up.

Detailed Description

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

In France, the observed vaccination coverage is very low for a complete regimen and has been declining since 2010. This low coverage makes it impossible to benefit from the efficiency observed in the other countries.

Indeed, a high HPV vaccination coverage rate would allow an epidemiologically significant impact with a reduction in cervical cancer mortality. In France, it is estimated that the vaccination of 80% of girls between the ages of 11 and 14 would reduce the incidence of 72% of CIN2 and 54% of CIN3.

Nevertheless, there is less data on patients who have been vaccinated in catch-up. These patients are 25 years of age or older in 2017, and make smears.

The aim of this study is to demonstrate whether HPV catch-up vaccination results in a decrease in the abnormal smear rate compared to the rate in unvaccinated patients.

If our study shows the benefits of catch-up vaccination, these data will help to mobilize doctors to vaccinate girls 15-19 years of age against HPV if they have not been able to benefit between 11 and 14 years as recommended.

* age of first sexual intercourse
* do they have a gynecological pathology

No interventions assigned to this group
