HPV is a virus, known as papillomavirus. There are more than 100 subtypes of HPV, which are divided into high-risk and low-risk types. High-risk HPV types can cause female diseases such as cervical cancer, vulvar cancer, vaginal cancer, anal cancer, head and neck cancer, oral cancer, etc.
Women have an 80% chance of encountering HPV infection in their lifetime, but 60% to 80% of them can clear the virus through autoimmune mechanisms in about 1 year. A small number of people carry the same virus for more than 2 years, and the chance of self-clearing is reduced. If it cannot be eradicated, it will lead to various diseases.
Since the launch of the HPV vaccine in 2006, after more than 10 years of long-term follow-up, the serum antibody titer level in the body is still high. Experts estimate that the vaccine will last for about 50 years. And the younger the age, the better the effect of asexual life.
However, HPV is the only effective way to prevent cervical cancer and prevent it. So as long as conditions permit, it is recommended that everyone get the HPV vaccine!
