Papillomavirus (HPV) is mainly infected through skin and mucous membrane contact, and the transmission routes include sexual transmission, mother-to-child transmission and contact transmission. According to experts, persistent high-risk HPV infection is directly related to the incidence of cervical cancer, among which over 70% of cervical cancer is caused by HPV16 and 18 infections. At present, HPV vaccination is the most economical and effective way to prevent cervical cancer. It should be noted that HPV vaccination cannot replace cervical cancer screening.
It is understood that five HPV vaccines have been approved in China, including three imported HPV vaccines and two domestic HPV vaccines. From the point of view of vaccine immunization program, two or three doses are needed, and there is no single dose vaccination in China at present. Experts said that according to the current mathematical model of clinical data, complete the whole immunization or achieve lifelong immunization. Vaccination can not only induce the body to produce humoral immunity, but also produce certain cellular immunity. Even if the titer of serum antibody in the body is reduced, as long as there is a virus attack, its immune memory can be immediately stimulated and high-concentration antibodies can be produced. In addition, experts said that as long as the whole vaccination of a vaccine is completed, there is no need to strengthen immunization at present. In order to eliminate cervical cancer, active prevention is our invincible "magic weapon". Experts call on female friends to take the initiative to pay attention to their health and actively prevent preventable diseases. (Proofreading/Liang Yaqin)
