Gardasil 9

The vaccine against the human papillomavirus

The vaccine against the human papillomavirus, GARDASIL 9, protects female sex from 9 to 26 years old against the infection of genital warts caused by 9 strains of HPV, which have been proven to have high incidence in the development of cervical, vaginal cancers, vulvar and anal. This vaccine also protects males between 9 and 26 years against anal cancer and genital warts caused by those same types of HPV.

Effectiveness of the vaccine

It is 97% effective in preventing infection with HPV types (6, 11, 16, 18, 31, 33, 45, 52 and 58), causing diseases of the cervix, vulva and vagina.

The medicament does not prevent 100% of cervical cancer types. Therefore, it is necessary for women to continue routine examinations for the detection of cervical cancer.

The medication does not cure cancer or genital warts, it only prevents infection if it is not HPV carrier yet.
