Can you still get cervical cancer after receiving the HPV 9-valent vaccine?

The term "9-valent vaccine" usually refers to the 9-valent HPV vaccine. After receiving the 9-valent HPV vaccine, one might still develop cervical cancer, although the risk is significantly reduced, as the vaccine does not provide 100% protection. The specific details are analyzed as follows:

1. Unlikely

The 9-valent HPV vaccine prevents infection by human papillomavirus (HPV), primarily targeting nine virus types: 6, 11, 16, 18, 31, 33, 45, 52, and 58, offering over 90% prevention efficacy. Individuals who do not carry genetic predispositions for cervical cancer, maintain good genital hygiene after vaccination, and undergo regular health checkups generally will not develop cervical cancer.

2. Possible

The 9-valent HPV vaccine does not protect against all HPV types. If a close relative has had cervical cancer, and if risky behaviors such as unprotected or multiple sexual partnerships persist after vaccination, or if gynecological inflammations remain untreated, there remains approximately a 10% chance of developing cervical cancer.

Following the recommended vaccination schedule and undergoing regular cervical cancer screening can help enhance preventive effectiveness.
