Screening after HPV vaccination can be considered after six months or a year, as some women are vaccinated with HPV infection, and at this time a review is needed after six months to determine if the HPV virus has persistent infection. Because persistent HPV infection can develop into high-grade intraepithelial neoplasia, regular follow-up and screening is needed to avoid the chance of developing safe lesions. For example, if you have not been screened for HPV and have been vaccinated for HPV, you may consider having a HPV vaccine screening one year later to determine if you have HPV infection. In the future, HPV screening can be performed every year or two years to monitor the presence of HPV infection dynamically.
