• Colposcopy is satisfactory based on visualization of the entire squamocolumnar junction and the upper limit of the entire aceto-white or suspected CIN disease area; lesions in ≤ 3 cervical quadrants (4 quadrant disease where the lesion occupies less than 50% of each quadrant will be considered for inclusion);
• Healthy subjects as judged by the Investigator based on medical history, PE, and normal results for an ECG, CBC, Serum Chemistries, CPK and urinalysis done up to 4 weeks prior to enrollment and administration of study drug;
• Women of child-bearing potential agree to remain sexually abstinent, use two medically effective methods of contraception (e.g. oral contraception, barrier methods, spermicide, intrauterine device (IUD)), or have a partner who is sterile (i.e., vasectomy) through 36 weeks (9 months);
• Able and willing to comply with all study procedures and voluntarily signs informed consent form

Exclusion Criteria:

• Unsatisfactory colposcopy defined as incomplete visualization of the entire squamocolumnar junction and the upper limit of the entire aceto-white or suspected CIN disease area;
• Pregnancy or breastfeeding
• Immunosuppression including any concurrent condition requiring the continued use of systemic or topical steroids at or near the injection site [deltoid, upper arm] (excluding inhaled and eye drop-containing corticosteroids) or the use of immunosuppressive agents. All other corticosteroids must be discontinued > 4 weeks prior to Day 0 of study vaccine administration; autoimmune disorders, transplant recipients;
• History of previous therapeutic HPV vaccination (individuals who have been immunized with licensed prophylactic HPV vaccines (e.g. Gardasil®, Cervarix®) are not excluded);
• Positive serological test for hepatitis C virus or hepatitis B virus surface antigen(HBsAg) or human immunodeficiency virus (HIV)

• Administration of any licensed vaccine within 2 weeks of enrollment( 4weeks for measles vaccine)
• Participation in a study with an investigational compound or device within 30 days of signing informed consent;
• Cardiac pre-excitation syndromes (such as Wolff-Parkinson-White);
• History of seizures (unless seizure free for 5 years);
• Tattoos, scars, or active lesions/rashes within 2 cm of the intended site of vaccination/EP or any implantable leads; or any implantable leads;
