There are three vaccines for HPV: Nine-valent: Protects against nine types of HPV Quadrivalent: Protects against four types of HPV Bivalent: Protects against two types of HPV All three HPV vaccines protect against the two types of HPV (types 16 and 18) that cause about 70% of cervical cancers and 90% of anal cancers. The nine-valent and quadrivalent vaccines protect against the two types of HPV (types 6 and 11) that cause more than 90% of genital warts, in addition to protecting against types 16 and 18. Only the nine-valent vaccine and quadrivalent vaccine are recommended for boys and men. Only the nine-valent vaccine is currently available in the United States.
