Can I get the nine-valent vaccine if I am over 26?

Ever since the HPV vaccine was approved and officially launched in our country, many female friends have never stopped questioning the HPV vaccine. Is the HPV vaccine safe? Is it true that vaccination can prevent cervical cancer? What are the differences between the bivalent, quadrivalent and nonavalent vaccines? Which HPV vaccine should a 26-year-old woman get? Can people over 26 years old get the nine-valent vaccine?

It is rather embarrassing to get the nine-valent cervical cancer vaccine at this age. In mainland China, only the quadrivalent vaccine is available. The nine-valent vaccine is limited to people aged 16-26, and the first shot must be given before the age of 26.5. If the actual effectiveness of the vaccine is taken into consideration, the nine-valent vaccine is naturally the best. In Hong Kong, there is no age limit for people over 9 years old. Just the price is slightly higher.

The most important difference between the nine-valent and quadrivalent cervical cancer vaccines is that the target groups for vaccination are different: the quadrivalent vaccine is suitable for women aged 20 to 45, while the nine-valent cervical cancer vaccine is suitable for women aged 16 to 26 in mainland China. Both are primarily for preventing cervical cancer.

According to statistics, the quadrivalent vaccine can prevent HPV infections of types 6, 11, 16, and 18. Wang Luwen, chief physician of the Department of Gynecology at the Provincial Maternal and Child Health Hospital, wrote that there are many types of HPV viruses, which are divided into high-risk and low-risk. Clinical data show that about 70% of cervical cancer patients can be detected with the above four viruses.

The 9-valent cervical cancer vaccine is based on the above two viruses and adds five low-risk HPV subtypes. The nine-valent vaccine is for nine subtypes of HPV6, 11, 16, 18, 31, 33, 45, 52, and 58. International scientific research data show that the nine-valent vaccine can prevent 90% of cervical cancer. .

Why should we increase the low-risk HPV subtypes?

Because low-risk HPV can also cause exogenous condylomata, flat condylomata, and mild cervical epithelial neoplasia on the skin around the anus of the genital system and under the vagina, it also poses a threat to health. In other words, the quadrivalent cervical cancer vaccine can prevent a large number of HPV infections, which can not only reduce the risk of cervical cancer, but also prevent common sexually transmitted diseases and skin diseases.

Is it necessary to get the nine-valent vaccine after getting the quadrivalent vaccine?

Theoretically, both the quadrivalent vaccine and the nine-valent vaccine can be administered. If you are only considering the prevention of cervical cancer and your ability to pay is limited, then the quadrivalent vaccine will be sufficient. If there are standards, there is no problem in getting the nine-valent vaccine again after getting the quadrivalent vaccine, but it is best to wait one year before getting the nine-valent vaccine after getting the quadrivalent vaccine.
