What is human papillomavirus?
What are the potential consequences of this infection?
The risks associated with HPV are significant. Among the 200 existing types of HPV, 12 are carcinogenic . Therefore, although most of these infections disappear within a few months, some can lead to cancer. We mainly think of cervical cancer , and for good reason: 100% of these cancers are caused by the human papillomavirus. However, these are not the only potential cancers.
This infection can also progress to cancer of the oropharynx, penis, anus, vagina or vulva. Contrary to popular belief, men are therefore also concerned since they represent 25% of those affected. It is also important to note that the vaccination of boys would also improve the protection of unvaccinated girls.

How does the vaccination take place?
- For girls and boys aged 11 to 14: 2 doses of Gardasil 9 should be taken. These must be spaced 6 to 13 months apart.
- For girls and men up to 19 years old, in catch-up: it is necessary to receive 3 doses. To do this, the first two doses must be spaced 2 months apart. The third dose should take place 6 months after the first dose.
- For men up to 26 years old who have had sex with other men: this is the same scenario as for catch-up, i.e. you must receive 3 doses of Gardasil 9 with an interval of 2 months between the first two doses . The third dose must be administered 6 months after the first.
The question of cervical screening
The issue of cervical cancer screening is of capital importance in the overall prevention strategy for these cancers. It is essential to understand that vaccination cannot replace screening . Indeed, vaccines do not confer total protection against all types of human papillomavirus (HPV) responsible for these cancers. This is why prevention is based on complementarity between vaccination and screening by cervico-uterine sample.
