Final answer:
The two licensed vaccines for HPV are Gardasil and Cervarix.
Step-by-step explanation:
The two licensed vaccines for HPV are Gardasil and Cervarix. Both vaccines were initially targeted for women but now it is recommended for both men and women to be vaccinated to achieve maximum efficacy, as HPV is sexually transmitted.
Gardasil vaccine protects against types 6, 11, 16, and 18 (associated with genital warts and cervical cancer), while Cervarix vaccine protects against types 16 and 18. Vaccination is recommended for boys and girls prior to sexual activity.
