Introduction
The 9-valent vaccine, also known as the 9-valent recombinant human papillomavirus (HPV) vaccine, typically helps prevent cervical cancer, vulvar cancer, vaginal cancer, anal cancer, and genital warts. The 9-valent recombinant HPV vaccine can effectively prevent cervical cancer caused by HPV types 16, 18, 31, 33, 45, 52, and 58.
The 9-valent vaccine, also known as the 9-valent recombinant human papillomavirus (HPV) vaccine, can typically prevent diseases such as cervical cancer, vulvar cancer, vaginal cancer, anal cancer, and genital warts after administration. If you have any concerns, it is recommended to seek medical advice in advance. Detailed explanations are as follows:
1. Cervical Cancer: The 9-valent recombinant HPV vaccine can effectively prevent cervical cancer caused by HPV types 16, 18, 31, 33, 45, 52, and 58. These high-risk HPV types are the main causes of most cervical cancer cases.
2. Vulvar Cancer: The 9-valent recombinant HPV vaccine can also prevent vulvar cancer caused by the aforementioned high-risk HPV types. Although vulvar cancer is relatively rare, its incidence has increased in recent years among young women.
3. Vaginal Cancer: The 9-valent recombinant HPV vaccine can prevent vaginal cancer caused by HPV types 16, 18, 31, 33, 45, 52, and 58. These HPV types are also among the primary causes of vaginal cancer.
4. Anal Cancer: The 9-valent recombinant HPV vaccine can prevent anal cancer caused by HPV types 16, 18, 31, 33, 45, 52, and 58. Anal cancer is more common among certain high-risk groups, such as immunosuppressed patients and men who have sex with men.
5. Genital Warts: In addition to preventing cancers caused by high-risk HPV types, the 9-valent HPV vaccine can also prevent genital warts caused by low-risk HPV types 6 and 11. Genital warts are a common sexually transmitted disease, and vaccination can reduce their incidence.
After receiving the 9-valent recombinant HPV vaccine, proper post-vaccination care is necessary. If adverse reactions occur, such as local pain, redness, swelling, fever, or headache, they are generally mild and will resolve on their own within a few days. If adverse reactions persist or worsen, or if severe allergic reactions occur, prompt medical attention is advised.
