Drivers providing bus, taxi or shared ride services (e.g., Uber, Lyft) and delivery services 4. User of public transportation (e.g., bus, train, subway) or public facilities (e.g. gyms) at least 3 times weekly 5. Nursing home staff or correctional facility staff 6. Retirement community residents or adult day program attendees who are regularly eating, socializing and/or exercising in common areas 7. Person 51 years or older living in a multigenerational (at least 3 generations) household 8. First responders (emergency medical technicians, police who are regularly assigned on patrol) Note: Firefighters typically use face shields and other protective gear but may be considered if they regularly assist with medical emergencies in the field 9. Health care workers with prolonged patient interaction (includes nurses and nursing assistants, medical assistants and technicians, respiratory therapists, physical therapists, social workers, dentists and dental hygienists) 10. Others, if in the opinion of the PI, the risk of COVID-19 exposure is comparable to the examples above.
6. Must meet one of the following criteria with respect to reproductive capacity: 1. Women who are post-menopausal as defined by reported spontaneous amenorrhea for ≥ 12 month; 2. Surgically sterile or has a partner who is sterile (i.e., vasectomy in males or tubal ligation, absence of ovaries and/or uterus in females). In the case of vasectomy, subjects should wait six (6) months post-vasectomy prior to enrolling; 3.

b) Long term use (≥7 days) of oral or parenteral glucosteroids at a dose of ≥20 mg/day of prednisone equivalent (use of inhaled, topical, nasal, otic, and ophthalmic corticosteroids are allowed) in the past 6 months;
c) Current or anticipated use of disease modifying doses of systemic anti-rheumatic drugs (e.g., azathioprine, cyclophosphamide, cyclosporine, methotrexate) and biologic disease modifying drugs such as TNF- α inhibitors (e.g., infliximab, adalimumab or etanercept) or others;
d) History of solid organ or bone marrow transplantation;
e) History of or current receipt of any other clinically significant immunosuppressive drugs.
f) Diagnosis of an autoimmune disease that may jeopardize the safety of the subject or require therapy that would interfere with study assessments or endpoint evaluation, or otherwise impact the validity of the study results.
9. Lack of acceptable sites for ID injection and EP considering the skin above the deltoid and anterolateral quadriceps muscles. The following are unacceptable sites:
a) Tattoos, keloids or hypertrophic scars located within 2 cm of intended administration site;
b) Implantable-Cardioverter-Defibrillator (ICD) or pacemaker (to prevent a life-threatening arrhythmia) that is located ipsilateral to the deltoid injection site (unless deemed acceptable by a cardiologist);
c) Any metal implants or implantable medical device within the electroporation site;
10. Blood donation or transfusion within 1 month prior to Day 0;
11. People who work remotely or in a socially distanced setting with minimal risk of exposure to SARS-CoV-2;
12. Prisoners or subjects who are compulsorily detained (involuntary incarceration);
13. Reported alcohol or substance abuse/dependence or illicit drug use (excluding marijuana use) within the prior 2 years;
14. Any illness or condition that in the opinion of the investigator may affect the safety of the subject or the evaluation of any study endpoint.

Brief Summary
It is a Phase 2/3 Randomized, Blinded, Placebo-Controlled Trial to Evaluate the Safety, Immunogenicity, and Efficacy of INO-4800, a Prophylactic Vaccine against COVID-19 Disease, Administered Intradermally Followed by Electroporation in Adults at High Risk of SARS-CoV-2 Exposure.
Given the continued number of cases globally, SARS-CoV-2 infections remain a seriousunmet medical concern. Appropriate measures to prevent SARS-CoV-2 infections,including its variants, are not yet widely available.
This study is conducted to Evaluate the efficacy of INO-4800 in the prevention of COVID-19 disease in subjects who are SARS-CoV-2 negative at baseline along with to evaluate the safety and tolerability of INO-4800.
Inovio Pharmaceuticals has developed INO-4800 as a DNA vaccine that contains 10 mg/mL of the DNA plasmid pGX9501 in 1X SSC buffer (150 mM sodium chloride and 15 mM sodium citrate). pGX9501 is a DNA plasmid expressing a synthetic consensus (SynCon®) sequence of the SARS-CoV-2 Wuhan-Hu-1 full-length Spike glycoprotein. The ID route of delivery has been selected for INO-4800 based on recent findings from multiple DNA vaccine development programs where ID delivery has driven equivalent if not superior humoral and cellular responses to IM delivery while improving tolerability (clinicaltrials.gov NCT02464670, clinicaltrials.gov NCT02431767). Following ID injection, the Inovio Pharmaceuticals EP device referred to as the CELLECTRA® 2000 for ID administration (3P-ID) device is used to facilitate DNA entry into the cells.
