Patient's question:
Female, 24 years old. I heard from a friend that the incidence of cervical cancer is particularly high now. If you get vaccinated, you can prevent it. How long should you wait to get another shot of HPV vaccine?Doctor's answer:
HPV 9-valent vaccine generally requires 3 doses of vaccination, with the interval time depending on the vaccine type. If it is a quadrivalent or 9-valent HPV vaccine, the second dose is administered on the same day, and the third dose is given 2 months after the second dose. The second dose is given 4 months after the third dose, which means one dose at 0, 2, and 6 months, totaling three doses. The 9-valent HPV vaccine can prevent infection from nine types of HPV. In addition to preventing the recurrence of cervical cancer, the 9-valent HPV vaccine can also prevent the recurrence of warts caused by various HPV infections, such as those on the vulva, vagina, and perianal area.
