Gardasil vaccine

The gardasil vaccine is a vaccine against human papillomavirus (HPV), which protects against infection by types 16 and 18 (these types of infection cause 70% of all cases of cervical cancer). This vaccine also protects against two types of HPV that do not cause cancer, types 6 and 11, but that cause about 90% of genital warts.
The efficacy in the prevention of precancerous lesions in this vaccine is greater than 92% in women who were not previously infected; that is, the vaccine is very effective.
