Why get the 9-valent HPV vaccine

Generally speaking, the reason for receiving the 9-valent HPV vaccine is to broaden protection, provide long-term immunity, and prevent genital warts, vaginal cancer, and cervical cancer. If any adverse symptoms occur after receiving the 9-valent HPV vaccine, it is recommended to seek medical attention promptly. Specific explanations are as follows:

1. Broader protection: The 9-valent HPV vaccine protects against nine types of HPV infection—types 6, 11, 16, 18, 31, 33, 45, 52, and 58. Compared to the bivalent and quadrivalent HPV vaccines, it offers a wider range of protection.

2. Long-term protection: After completing the full series of 9-valent HPV vaccinations according to schedule, protection typically lasts 10–20 years, providing long-lasting preventive benefits.

3. Prevention of genital warts: Infection with HPV types such as 6 and 11 can easily lead to genital warts. Therefore, receiving the 9-valent HPV vaccine reduces the likelihood of developing this condition.

4. Prevention of vaginal cancer: High-risk HPV types such as 16 and 18 can lead to vaginal cancer. Since both of these types are covered by the 9-valent HPV vaccine, vaccination helps prevent vaginal cancer.

5. Prevention of cervical cancer: Infection with high-risk HPV types such as 16 and 18, or other types including 31, 33, 45, and 51, increases the risk of cervical cancer. Thus, timely administration of the 9-valent HPV vaccine helps protect against cervical cancer.

After receiving the 9-valent HPV vaccine, it is recommended to remain at the clinic for observation for 30 minutes before leaving. At home, avoid touching or washing the injection site with water to prevent local infection and potential discomfort.
