• Histories or on-going conditions of malignancy, except for non-melanoma skin cancer, excised more than 2 years ago.
• History of abnormal cervical biopsy results (showing cervical intraepithelial neoplasia or worse) or cervical disease (ie, surgical treatment for cervical lesions) within 5 years prior to Screening Visit.
• History of a positive test for HPV infection.
• Histories of severe allergic or anaphylactic reactions, or sensitivity to the IP or its constituents.

• Systolic blood pressure ≥ 140 mmHg and/or a diastolic blood pressure ≥ 90 mmHg before vaccination.
• Receipt of systemic immunosuppressants or immune-modifying drugs for > 14 days in total within 6 months prior to Screening Visit (for corticosteroids ≥ 20 mg/day of prednisone equivalent). Inhaled/nebulized, intra-articular, intrabursal, or topical (skin or eyes) corticosteroids are permitted.
• Receipt of immunoglobulins and/or any blood products within the 3 months prior to the first vaccination or planned administration during the study period.
