* Age ≥ 18 years
* Baseline Eastern Cooperative Oncology Group performance status of 0 or 1 at the time of enrollment.
* Patients must have adequate organ function at the time of enrollment as defined by the following parameters:
* White blood cell count ≥ 3,000 cells/uL
* Absolute lymphocyte number ≥ 500 cells/uL
* Absolute neutrophil count ≥ 1,500 cells/uL
* Platelets ≥ 90,000 cells/uL
* Hemoglobulin ≥ 9 g/dL
* Total bilirubin \< 3 X the institutional limit of normal
* Aspartate Aminotransferase (AST) and Alanine Aminotransferase(ALT) \< 3 X the institutional limit of normal
* Creatinine \< 2.5 X the institutional limit of normal
* Women of child-bearing potential must agree to use long acting contraception (e.g. tubal ligation, intrauterine device or hormonal implant) or two forms of contraception (e.g. barrier method, oral contraceptives) prior to study entry and for 3 months after final vaccination.
* Ability to understand and the willingness to sign a written informed consent document.
* Able to adhere to the study visit schedule and other protocol requirements.

Exclusion Criteria:

* Histologic evidence of CIN2, cervical intraepithelial neoplasia 3 (CIN3), adenocarcinoma in situ or malignancy.
* Patients with a diagnosis of immunosuppression or active systemic use of immunosuppressive medications such as steroids.
* Patients who are receiving any other investigational agents within 28 days prior to the first dose of study vaccine.
* Patients with an uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
* Patients with a history of systemic autoimmune disease such as multiple sclerosis or systemic lupus erythematosus (SLE), but exclusive of a history of thyroiditis, psoriasis, Sjogren's, or inflammatory bowel disease.
* Patients who are pregnant or breast feeding or plan to become pregnant within 12 months of first study treatment.
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to pBI-11 DNA vaccine.
* Patient with active infection of, or receiving treatment for Human Immunodeficiency Virus (HIV), Hepatitis C Virus (HCV), or Hepatitis B Virus (HBV).
* History of prior malignancy with disease free interval \<5 years; however, individuals with completely resected basal cell or squamous cell carcinoma of the skin within this interval may be enrolled.
* Participants with metal implant(s) at the site of injection or any electronic stimulation device, such as cardiac demand pacemakers, automatic implantable cardiac defibrillator, nerve stimulators, or deep brain stimulators.
* Participants with any chronic or active neurologic disorder, including seizures and epilepsy, excluding a single febrile seizure as a child or episode of seizure in pregnancy due to eclampsia.
* Participants with syncopal episode within 12 months of screening, excluding fainting for a known and unrelated cause such as anemia which has been resolved.
* Administration of immunoglobulins and/or any blood products within the 120 days preceding study entry or planned administration during the study period.
* Participants with a skin-fold measurement of the cutaneous and subcutaneous tissue for all eligible injection sites (vastus lateralis muscles with intact lymph drainage) exceeds 50 mm.
* Participants in whom the ability to observe possible local reactions at the injection site (lateralis region) is, in the opinion of the investigator, unacceptably obscured due to a physical condition or permanent body art.
