Introduction
Diseases caused by human papillomavirus (HPV) have become a global public health problem, and currently the only prevention method in the world is vaccines. The nine-valent HPV vaccine is the latest HPV vaccine that can prevent nine high-risk types of HPV infection, but whether it can protect us for life remains to be explored.
Research progress on long-term immune persistence
The immunogenicity and protective effect of the nine-valent HPV vaccine have always attracted much attention, because only long-term studies can prove whether it can provide lifelong protection. To date, the results of multiple long-term immunity persistence studies have been released. Among them, a study on the nine-valent HPV vaccine for women aged 15-26 showed that the immunogenicity of the vaccine was still higher than the critical value after 10 years and could provide long-term protection. However, since the nine-valent HPV vaccine has just been launched, long-term follow-up data are still insufficient. Therefore, we need more research to verify whether the nine-valent HPV vaccine can protect us for life.
Preventive effect of nine-valent vaccine
The nine-valent HPV vaccine is a preventive vaccine that can prevent infection by nine high-risk types of HPV, including all cancer-causing types and several types that cause wart-like lesions. A number of large-scale clinical trials have proven internationally that the nine-valent HPV vaccine has an excellent preventive effect and can effectively prevent HPV infection in more than 99% of vaccinated people. Therefore, if we ensure vaccination with the nine-valent HPV vaccine, even if it cannot protect us for life, it can protect us from HPV infection for a longer period of time and reduce the risk of HPV infection.
Other measures to stay healthy
In addition to vaccination with the nine-valent HPV vaccine, we can also take other measures to stay healthy. First of all, correct sexual behavior education is very important to prevent HPV infection. Secondly, regular HPV testing and early detection and treatment of HPV infection are also key. In addition, maintaining good living habits, such as regular exercise, reasonable diet, not smoking or drinking, can also improve the body\’s immunity and resistance, and play an important auxiliary role in preventing HPV infection.
Conclusion
As an important means to prevent HPV infection, the nine-valent HPV vaccine can effectively prevent nine high-risk types of HPV infection. However, we still need more research and time to verify whether it can provide lifelong protection. Therefore, even if we have received the nine-valent HPV vaccine, we still need to maintain good living habits, undergo HPV testing and receive regular treatment to maintain good health. Only through the combined effect of multiple means can we better prevent HPV infection and protect our health.
