The difference between 2-valent, 4-valent and 9-valent HPV vaccines

When it comes to cervical cancer, many female friends think of cervical cancer vaccine, because there is only targeted prevention vaccine for cervical cancer in the world. At present, cervical cancer vaccines are divided into 2-valent, 4-valent and 9-valent. So what are the differences between these cervical cancer vaccines and where are the differences?

What are the differences between the bivalent, quadrivalent and nonavalent cervical cancer vaccines? What is their difference? After understanding the HPV virus, because there are many types of HPV viruses, the viruses that cause cervical cancer are some of them, not all HPV viruses. Therefore, specific cervical cancer vaccines are developed specifically for the HPV viruses that cause the most common cervical cancer. Therefore, cervical cancer vaccines are divided into bivalent, quadrivalent and nonavalent: 2-valent cervical cancer (HPV) vaccine, bivalent cervical cancer vaccine refers to the two types HPV16 and HPV18. 80% of cervical cancers are caused by these two HPV viruses; the target group for 2-valent cervical cancer vaccine is women aged 9-25. Women who have not had sex can effectively prevent the occurrence of cervical cancer after being injected with the 2-valent cervical cancer vaccine.

What are the differences between the 2-valent, 4-valent and 9-valent cervical cancer vaccines? Quadrivalent cervical cancer (HPV) vaccine: The quadrivalent cervical cancer vaccine is based on the 2-valent cervical cancer vaccine, with the addition of low-risk HPV6 and HPV11. Even low-risk HPV viruses can cause relative harm to humans. Compared with the 2-valent cervical cancer vaccine, the 4-valent cervical cancer vaccine has a wider prevention scope and the age range of the vaccinated group is also wider. The target age group for the 4-valent vaccine is women aged 20-45. The launch of the quadrivalent cervical cancer vaccine can protect more female friends.

What are the differences between the 2-valent, 4-valent and 9-valent cervical cancer vaccines? The 9-valent cervical cancer (HPV) vaccine: The 9-valent cervical cancer vaccine adds five HPV viruses, HPV31, HPV33, HPV45, HPV52 and HPV58, to the quadrivalent cervical cancer vaccine. The nine-valent cervical cancer vaccine has been approved for sale in China and has been very popular among female friends. The target group for the nine-valent cervical cancer vaccine is female friends aged 16-26. The nine-valent cervical cancer vaccine can prevent 90% of cervical cancer.

The above is a detailed discussion on "What are the differences between the 2-valent, 4-valent and 9-valent cervical cancer vaccines".
