The human papilloma virus infection is the most frequent sexually transmitted infection around the world. In the vast majority of cases, these are inapparent infections that disappear spontaneously. In some cases, the HPV infection persists and can generate anogenital warts or cancer.

In France, the papillomavirus is responsible for 6000 new cases of cancer/year with several possible localizations : cervical, anal, penile, oropharyngeal, vulvar or vaginal. Among them, 4580 new cases of cancer/year occur in women, and half of them are diagnosis of cervical cancer. A quarter of cancers caused by papillomavirus occur in men.

In France, the commercialization of anti-HPV vaccine in 2007 was addressed only to girls, in order to gain a group immunity that would therefore protect the boys. This vaccination did not achieve the cover immunization target that were announced: the objective was fixed at 60% of vaccination coverage and at the end of 2018, only 24% was achieved on the complete vaccination schedule. In December 2019, the French National Authority for Health recommended the anti-HPV vaccinations in girls and boys.

This qualitative study evaluates parents' opinion regarding the vaccination and the HPV. Parent's eligible to participate in this study are those with boys between 11 and 14 years old.
