Gardasil 9 HPV Vaccine Description
Gardasil 9 consists of human papillomavirus (HPV) proteins, Types 6, 11, 16, 18, 31, 33, 45, 52, and 58, amorphous aluminum hydroxyphosphate sulfate, yeast protein, sodium chloride, L-histidine, Polysorbate 80, sodium borate, and water for injection.
HPV infections can lead to certain cervical cancers. Many females with cervical cancer were probably exposed to cancer-causing HPV types in their teens and early 20s. Unlike some other cancers, cervical cancer is not thought to be passed down through family genes.
The cervix is the lower part of the uterus that connects to the vagina. When a female is infected with these types of HPV, and the virus doesn't go away on its own, abnormal cells can develop in the cervix. If these abnormal cells are not found early through routine cervical cancer screening and treated, then cervical cancer can develop.
Additionally, males can get HPV, causing anal and throat cancers, and genital warts.
