Cervical cancer is one of the major threats to women's health worldwide, and human papillomavirus (HPV) infection is the leading cause of the disease. Although HPV vaccination provides an effective means to prevent cervical cancer, there are still cases of HPV positive and even cervical cancer developed after vaccination. This article will explain in detail what the HPV vaccine does, why it's important, and why it's important to be vigilant after vaccination.
Role and limitations of HPV vaccine
The 9-valent HPV vaccine currently on the market is able to protect against many high-risk types of HPV, but not all types of HPV that cause cancer. There are more than a dozen known types of cancer-causing HPV, and vaccine coverage is limited. In addition, the vaccine is not 100% effective, especially for individuals who may have had occult HPV infection prior to vaccination.
Age and effect of vaccination
Girls between the ages of 9 and 14 are most effective with HPV vaccination. Vaccination at this age group provides the greatest protection, but even then, the vaccine is not absolute in preventing cervical cancer and precancerous lesions.
Timeline of HPV infection
It usually takes a long time from high-risk HPV infection to the onset of lesions, in most cases more than ten years. Therefore, some women may have been infected with HPV before vaccination, which may explain why some people are still diagnosed with cervical cancer 2 to 3 years after vaccination.
Differences in individual and group protection rates
The HPV vaccine protection rate is based on population statistics, and for individuals, the vaccine is either completely protective or non-protective. This means that vaccinated individuals can still develop cervical cancer.
Protection is not a reason for indulgence
HPV vaccination only provides an additional layer of protection for the individual and is not an absolute guarantee. Therefore, even if you are vaccinated, you should maintain a healthy lifestyle, avoid high-risk sexual behaviors, such as avoiding multiple sexual partners, and use condoms throughout sex.
The importance of regular screening
In addition to getting vaccinated and maintaining a healthy lifestyle, regular cervical cancer screenings are equally important. Screening allows for early detection of abnormalities and timely treatment, thereby significantly reducing the incidence and mortality of cervical cancer.
The HPV vaccine is an important means of preventing cervical cancer, but it is not foolproof. A combination of vaccination, a healthy lifestyle, and regular screening provides maximum protection for women's health. Knowing this information can help every woman make more informed health decisions.
