Several types of HPV vaccines are available, including Gardasil, Gardasil 9, and Cervarix. Gardasil 9 is the most widely used and provides protection against nine HPV types: HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58. Gardasil protects against four types (HPV 6, 11, 16, and 18), and Cervarix protects against two types (HPV 16 and 18). The choice of vaccine may depend on availability and individual healthcare recommendations.
