Brief Summary:
DNA vaccines, which are small pieces of DNA also known as plasmids, have several advantages over traditional vaccines such as live attenuated virus and recombinant protein-based vaccines. DNA vaccines appear to be well tolerated in humans. Therefore, the investigators have developed our DNA vaccine, VGX-3100, to include plasmids targeting E6 and E7 proteins of both HPV subtypes 16 and 18. The investigators have chosen to deliver our candidate vaccines via electroporation (EP) using the CELLECTRA constant current device to deliver a small electric charge following intramuscular (IM) injection, since animal studies have shown that this delivery method increases the immune response to our DNA vaccine leading to a decrease in the size of tumors caused by HPV 16 and 18. In study HPV-001, the vaccine was given to subjects with a history of CIN 2 and 3 who had been previously treated by surgery. This study is proposed to vaccinate the same subjects with a fourth dose of the VGX-3100 to determine the safety and immune response.

Arm Intervention/treatment
Experimental: 6mg of DNA/dose
Subjects who have previously received a 3 dose series of VGX-3100 containing either 0.6, 2 or 6mg DNA/dose will receive a fourth dose of VGX-3100 containing 6mg of DNA/dose administered via IM injection + electroporation at Day 0
Biological: VGX-3100
DNA plasmid delivered via IM injection + electroporation using CELLECTRA device

Primary Outcome Measures :
  1. Safety and tolerability of a fourth dose of VGX-3100 [ Time Frame: through Month 6 (end of study) ]
    Safety and tolerability of a fourth dose of VGX-3100, administered by IM injection with EP to adult females who have been previously immunized with three doses of VGX-3100

Secondary Outcome Measures :
  1. Humoral and cellular immune responses to VGX-3100 [ Time Frame: through Month 6 (end of study) ]
    Humoral and cellular immune responses to VGX-3100 in blood samples obtained from study subjects after a fourth dose of VGX-3100 (6 mg) in adult female subjects who have been previously vaccinated with a three dose series of VGX-3100 containing 0.6, 2 or 6 mg of DNA/dose.
