What are the effects of cervical cancer vaccines? Do you understand these preventive measures
The occurrence of cervical cancer is particularly harmful to patients. While recognizing its impact, it is also important to pay attention to reasonable prevention. Cervical cancer vaccine is one of the prevention methods, and we should also roughly understand it.
How effective is the cervical cancer vaccine
Although the cervical cancer vaccine is not perfect, there is no doubt about its practical application value. It is undeniable that mainland women are enthusiastic about receiving cervical cancer vaccines in Hong Kong and Macao. Many studies have shown that after receiving the vaccine, the HPV infection rate of uninfected women significantly decreases. After receiving the vaccine, the body's immune function against the virus will also be enhanced.
The HPV vaccine for preventing cervical cancer has been approved in China. The news sparked heated discussions as many women believed that getting a cervical cancer vaccine was a one-time solution, and having a vaccine in their bodies meant they no longer had to worry about developing cervical cancer. This is not the case. according to
Experts introduce that cervical cancer is the only cancer that can be prevented by vaccines. Cervical cancer is the most deadly and easily preventable type of female cancer in the world. The medical community has identified human papillomavirus (HPV) as the main cause of cervical cancer in women, and 99% of cervical cancer is related to HPV infection. There are currently over 200 known types of HPV, most of which are unrelated to cervical cancer, and there are over a dozen high-risk types associated with cervical cancer. Among them, hpv16 and hpv18 genotypes have the highest risk and can cause approximately 70% of cervical cancer. The currently approved HPV vaccines are mainly targeting HPv16 and HPv18.
Experts say that cervical cancer vaccines cannot be 100% prevented, and 70% to 75% of cervical cancer is caused by infection with HPv16 or HPv18. Vaccines marketed in China can effectively prevent cervical cancer induced by these two types of viruses. In addition, the vaccine also has a good cross effect, which can prevent 90% to 95% of genital warts, as well as low-risk virus infections caused by HPv9 and HPv11 types. However, this does not mean that all cervical cancer viruses can be intercepted by vaccines. 99% of cervical cancer is associated with HPV infection, with over 200 confirmed HPV viruses and over a dozen high-risk types associated with cervical cancer, including 16, 18, etc. According to the proportion of cervical cancer infected with high-risk HPV types 16 and 18, at least 25% of cervical cancer cannot be prevented through existing vaccines, which means that vaccination cannot guarantee infection with other high-risk viruses.
