Gardasil: HPV prevention that matters for both men and women (Seocho-gu OB/GYN)

Many people have postponed Gardasil vaccination, thinking, "Isn't it just for women?" To put it simply, Gardasil is a vaccine recommended for both men and women, and it can help prevent various HPV-related diseases, including cervical cancer.

What is HPV?

HPV stands for Human Papillomavirus, and it is primarily transmitted through sexual contact. It can cause warts on the skin and mucous membranes, and some high-risk types have been reported to be associated with cancers in various parts of the body.

The problem is that there are often no clear symptoms even after infection. Many people live unaware of their infection until it is incidentally discovered during a routine check-up. In the clinic, it's not uncommon for patients to ask, "I didn't have any particular discomfort, so why?" Therefore, regular HPV testing and vaccination are recommended together.

HPV can be transmitted without symptoms, making it difficult to feel reassured based solely on the presence or absence of symptoms. A combined approach of testing and vaccination can be helpful.

What Does Gardasil Prevent?

Gardasil is a vaccination aimed at preventing HPV infection. It can help prevent various HPV-related diseases such as vaginal cancer, vulvar cancer, anal cancer, and genital warts (condyloma), and is recommended for both men and women aged 9 and older.

The reason why vaccination is recommended for men is clear. HPV is transmitted bidirectionally, so preventing it in only one partner makes it difficult to sufficiently break the chain of infection. It is a choice for your partner, and it is also related to preventing anal cancer and genital warts in yourself.

What is the Difference Between Gardasil 4 and Gardasil 9?

They are divided into Gardasil 4-valent and Gardasil 9-valent depending on the range of HPV types they prevent.

Which vaccine is right for your situation may vary depending on your age, vaccination history, and health status. If you are unsure about your choice, we recommend deciding through consultation during your medical appointment.

How Many Doses Are Needed?

Gardasil is not a one-time shot; it is administered in 2 or 3 doses depending on age.

• For those aged 9 to 14, two doses are administered, with the second dose given approximately 6 months after the first.
• For those aged 15 and older, three doses are administered: the second dose approximately 2 months after the first, and the third dose approximately 3 months after the second.

The vaccination schedule can be adjusted according to individual circumstances, so confirming the next appointment at the time of the first dose can help reduce omissions.

Is Vaccination Alone Enough?

While vaccination is a powerful preventive measure, it does not prevent all HPV types without exception. Therefore, even after vaccination, it is recommended to combine regular cervical cytology tests and check-ups as a safe management approach.

If you are already receiving treatment for concerns such as HPV and chronic vaginitis, or if you suspect genital warts and are considering condyloma drug treatment, it is helpful to discuss your vaccination timing and testing plan together.

What if I Missed the Vaccination Window?

While vaccination before sexual activity is considered ideal, preventive effects can still be expected even if vaccinated afterward. Rather than hesitating with "Is it already too late?", it is better to establish a vaccination plan suitable for your age and condition. Since there are individual differences in effectiveness and suitability, we recommend confirming the right approach for you through a medical consultation.
