Signs and Symptoms of HPV Vaccination

In most cases, infection with human papillomavirus does not cause symptoms. People who are infected with genital HPV often do not even know that they are infected and that they might be spreading it to their sexual partners.

In other cases, HPV infection poses a serious health risk. Certain types of HPV are more likely to cause genital warts, cervical cancer and other types of genital cancers (e.g., penile cancer, vaginal cancer), anal cancer, and oral cancer.

HPV infection may cause abnormal cell changes and warts (benign skin growths). For example, genital HPV can cause lesions or bumps in the genital area. An abnormal Pap test (also called a Pap smear) that shows changes in cervical cells (cervical dysplasia) may be a sign of early cervical cancer.
