Gardasil and Gardasil 9 are vaccines that protect against different types of the HPV virus, responsible for the emergence of cervical cancer, and other changes such as genital warts and other types of cancer in the anus, vulva and vagina.
Gardasil is the oldest vaccine that protects against 4 types of HPV virus - 6, 11, 16 and 18 - and Gardasil 9 is the most recent vaccine against HPV that protects against 9 types of the virus - 6, 11, 16, 18, 31, 33, 45, 52 and 58.
This type of vaccine is not included in the vaccination plan and, therefore, is not administered free of charge, having to be purchased at pharmacies. Gardasil, which was developed earlier, has a lower price, but it is important for a person to know that it only protects against 4 types of the HPV virus.
