Cervical cancer as a female health killer, every year because of cervical cancer and death of women are not a few, the most effective way to prevent cervical cancer is vaccination. So how old is the best vaccination age for cervical cancer vaccine?
China has finally approved the listing of HPV vaccine to prevent cervical cancer. It is understood that the U.S. Food and Drug Administration approved the application age of HPV vaccine to be 9-26 years old. Can I be vaccinated when I am over 26?
Wang yuedan, deputy director of Immunology Department of Peking University Medical Department, thinks that if you don't have sex, you can get vaccinated.
What is the relationship between HPV and cervical cancer? It is understood that human papillomavirus is one of the family of papillomavirus, referred to as HPV. At present, there are more than 100 different types of HPV, most of which are considered as' low risk ', and they are not associated with cervical cancer. However, 14 HPV types are classified as' high risk 'because they have been shown to cause almost all cervical cancers. Two of the most dangerous strains, HPV-16 and HPV-18, can cause about 70% of cervical cancer cases.
It is worth noting that even if the cervical cancer vaccine is vaccinated, it should still be screened regularly, because there are more than 100 subtypes of HPV, and more than 10 high-risk subtypes related to cervical cancer, and the vaccine is only aimed at some of them.
However, based on the good clinical protective effect and safety data of the HPV vaccine, the WHO (WHO) encourages the use of HPV vaccine in the appropriate population to reduce the incidence of cervical cancer.
The World Health Organization (who) recommended 9-12-year-old vaccination population. The age of application of HPV vaccine approved by FDA is 9-26 years old. The American Association of Obstetricians and gynaecologists recommends that women between the ages of 9 and 26 be vaccinated, while men or women over the age of 26 need not be vaccinated.
Wang yuedan, deputy director of Immunology Department of Peking University Medical Department, believes that the recommended vaccination period refers to the period before sexual behavior, after which the effect of vaccination may not be significant. He explained that the rate of HPV infection is particularly high when women have sex. The vast majority of people have invisible infections and can form antibodies, so there is no need to vaccinate. If you don't have sex, you can get vaccinated.
The United States Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) do not recommend HPV vaccination for people over 26 years old. The main reason is not that HPV vaccination does not work for people over 26 years old, but the lack of research results at this stage.
According to the Hong Kong Cancer Prevention Association, if the vaccination can still be carried out over the age of 26, even if HPV infection already exists, it will rarely infect all the corresponding subtypes of the vaccine. Generally speaking, whether to vaccinate more than 26 years old mainly depends on their own sexual life. If they haven't had sex, they can be vaccinated; for married people or people with fixed sexual partners, vaccination is of little significance.
