Nine-valent vaccine
Hello Dr.
Wu,
I have been treating genital warts for over a year now, and recently the number of recurring lesions has significantly decreased.
Following my attending physician's advice, I have started receiving the nine-valent HPV vaccine.
I would like to ask you:
1.
I understand that the nine-valent vaccine is preventive and not a treatment, but will receiving the vaccine during the infection period still be beneficial?
2.
If I do not experience any recurrences for a period of time, does that mean that the virus is no longer present in my body?
Thank you very much for your clarification.
I greatly appreciate it.

More Info
The Nine-Valent HPV vaccine (Gardasil 9) is a significant advancement in the prevention of HPV-related diseases, including cervical cancer and genital warts. Your questions about the vaccine's role during an active infection and the implications of symptom resolution are quite pertinent.
1. Effectiveness of the Nine-Valent Vaccine During Active Infection: While it is true that the Nine-Valent HPV vaccine is primarily designed for prevention rather than treatment, receiving the vaccine during an active HPV infection can still provide benefits. The vaccine protects against nine strains of HPV, including the high-risk types (16, 18) that are responsible for the majority of cervical cancers, as well as low-risk types (6, 11) that cause genital warts. Even if you are currently infected with one or more HPV types, the vaccine can help protect against other types that you may not have been exposed to yet. This is particularly important because HPV infections can be asymptomatic, and individuals may not be aware of all the strains they have been exposed to. Therefore, while the vaccine will not eliminate an existing infection, it can help prevent future infections and reduce the risk of developing HPV-related diseases.
2. Implications of No Recurrence of Symptoms: If you have not experienced any recurrence of genital warts over a period of time, it does not necessarily mean that the virus has been completely eradicated from your body. HPV is known for its ability to remain dormant in the body, and many individuals can clear the virus naturally over time, especially if they have a healthy immune system. Studies suggest that approximately 70-90% of HPV infections will resolve on their own within two years. However, the absence of visible symptoms does not guarantee that the virus is no longer present. Regular follow-ups with your healthcare provider, including monitoring for any changes or symptoms, are essential.
In summary, while the Nine-Valent HPV vaccine is not a treatment for existing infections, it can provide significant preventive benefits against other HPV types. Additionally, the absence of symptoms does not confirm the complete clearance of the virus, so ongoing monitoring is advisable.
In the context of HPV management, it is crucial to maintain open communication with your healthcare provider, adhere to recommended follow-up schedules, and discuss any concerns regarding your health and the implications of HPV. Vaccination, regular screenings, and awareness of your health status are key components in managing HPV effectively and reducing the risk of associated complications.
