Question: does the hpv vaccine protect against hpv?
Answer: Gardasil protects against 4 types of HPV: 6, 11, 16 and 18. Between them, types 16 and 18 are the cause of most cervical cancers in the UK (more than 70%). These types of HPV also cause some anal and genital cancers, and some cancers of the head and neck.
