Exclusion Criteria

1. Any important protocol deviation in Study GEN-003-002.
2. Use of HSV-2 antiviral therapy within 14 days before the beginning of Swab Collection Period 1.
3. Use of topical steroids or antiviral medication in the anogenital region within 14 days before the beginning of Swab Collection Period 1.
4. Use of tenofovir, lysine, or other medication or supplement known or purported to affect HSV outbreak frequency or intensity within 14 days before the beginning of Swab Collection Period 1.
5. Immunocompromised individuals, including those receiving immunosuppressive doses of corticosteroids (more than 20 mg of prednisone given daily or on alternative days for 2 weeks or more within 6 months before the Visit 1, any dose of corticosteroids within 30 days before Visit 1, or high-dose inhaled corticosteroids [>960 µg/day of beclomethasone diproprionate or equivalent]) or other immunosuppressive agents.
6. Presence or history of autoimmune disease, regardless of current treatment.
7. Receipt of a vaccine containing HSV-2 antigens other than GEN-003.
8. Pregnant women.
9. History of drug or alcohol abuse that, in the opinion of the Investigator, would interfere with the patient's ability to comply with the requirements of the study.
10. Onset of an AESI since Month 12 in study GEN-003-002.
11. Other active, uncontrolled comorbidities that, in the opinion of the Investigator, would make the subject unsuitable for the study or unable to comply with the study requirements.
