I got cervical cancer after taking the 4-valent vaccine

If you get cervical cancer after getting the quadrivalent HPV vaccine, it may be caused by infection before vaccination, infection with other HPV types, weakened vaccine protection, incomplete vaccination, other risk factors, etc. It is recommended to seek medical attention in time and follow the doctor's advice for treatment such as surgery or chemotherapy.

1. Infection before vaccination: If you have been infected with HPV16 or 18 before vaccination, the vaccine may not prevent the infection from developing into cervical cancer.

2. Infection with other HPV types: Cervical cancer may be caused by other high-risk types not covered by the HPV vaccine, such as HPV31, 33, 45, etc.

3. Weakened vaccine protection: Although HPV vaccines generally have long-term protective effects, the protection may weaken over time, especially many years after vaccination.

4. Incomplete vaccination: If the vaccination procedure is not completed or insufficient immune response is produced after vaccination, the protective effect of the vaccine may be affected.

5. Other risk factors: The occurrence of cervical cancer may also be related to other risk factors such as smoking, immunosuppression, multiple sexual partners, early sexual activity, and long-term use of contraceptives.

Cervical cancer is a relatively serious malignant tumor. It can be treated surgically and combined with chemotherapy to control the progression of the disease.
