How long does the Nine-Stage Anti-Cancer Vaccine remain effective?

The 9-valent anti-cancer vaccine is estimated to provide protection for approximately 10 to 20 years; however, the exact duration is not fixed and varies depending on individual physiology. Specific details are as follows:

1. As the vaccine has only recently been introduced to the market, its definitive duration of protective efficacy has not yet been established and requires further clinical trials for confirmation. Nevertheless, the bivalent, quadrivalent, and nonavalent HPV vaccines are all inactivated vaccines. Although their valences differ, their durations of protection are generally similar—approximately 10 to 20 years.

2. The 9-valent HPV vaccine can prevent up to 90% of cervical cancers and genital warts, as well as approximately 95% of anal cancers. Even after vaccination, regular cervical cancer screening remains essential. Importantly, HPV vaccines cannot treat existing HPV infections and therefore do not confer lifelong immunity. Thus, routine cervical cancer screening must continue post-vaccination to ensure early detection and prevention.

In daily life, individuals should also maintain a light, balanced diet and avoid spicy or otherwise irritating foods.
