Patient's question:
Female, 19 years old. My mom told me to get the nine-valent cervical cancer vaccine, but I'm still young, so I want to ask: What are the differences between the four, nine, and nine-valent HPV vaccines?Doctor's answer:
The cervical cancer vaccine, known as the human papillomavirus (HPV) vaccine, has the second-highest incidence rate after breast cancer. China is a severe hotspot for cervical cancer, accounting for 28% of global cervical cancer patients. The cervical cancer vaccine can prevent the majority of cervical cancer-causing viruses. It is divided into bivalent, quadrivalent, and nonavalent vaccines. The bivalent vaccine can prevent the two most high-risk cervical cancer-causing viruses, namely HPV 16 and HPV 18. The quadrivalent vaccine enhances protection against two low-risk HPV subtypes, HPV 6 and HPV 11. The nonavalent vaccine can almost prevent all cervical cancer-causing vaccines.
