TRIAL DESCRIPTION
Public title A randomized study, assessing the safety and immunogenicity of a COVID-19 vaccine in healthy adults
Official scientific title A Randomized, Observer-Blind, Dose-Escalation, Placebo-Controlled Phase 1 Clinical Trial of COVAC-1 in Generally Healthy Adults
Brief summary describing the background and objectives of the trial VIDO has developed a vaccine called COVAC-1. The study vaccine contains a portion of the SARS-CoV-2 spike protein, called S1. Spike proteins are typically club-shaped in shape and project from the surface of the virus. The spike protein is the part of the virus that attaches to the surface of host cells, which are normal cells in your body which have certain molecules or chemicals that promote attachment. COVAC-1 contains an adjuvant [ad-joo-van-t] called TriAdj. An adjuvant is a compound that is added to a vaccine to help the vaccine produce a better immune response. These three components working together improve the body’s response to the S1 protein. The vaccine is expected to stimulate the body to make antibodies (which are proteins that circulate in the blood and recognize foreign substances like viruses and neutralize them) against the S1 protein. The antibodies will recognize the viral spike protein if the body is exposed to the virus and prevent or reduce the severity of COVID-19 illness. In animal studies, the immune response generated by the COVAC-1 vaccine was able to protect the vaccinated animals against a severe SARS-CoV-2 infection. This research study is being done to assess the safety and ability of the investigational COVAC 1 vaccine to generate an immune response against SARS-CoV-2.

Good general health as determined by screening evaluation no greater than 30 days before injection of first dose; Note: Participants who are overtly healthy as determined by medical evaluation or are considered medically stable according to the judgment of the Investigator.

Presence of any febrile illness or any known or suspected acute illness on the day of any immunization; 2. Any immunodeficiency (congenital or acquired) disease, disorder, or finding that may significantly increase the risk of study participant or, in the Investigator’s judgment, make the participant inappropriate for the study; 3. Clinically significant bleeding disorder (e.g., clotting factor deficiency, coagulopathy or platelet disorder), or prior history of significant bleeding or bruising following IM injections or venipuncture; 4. Receiving systemic immunosuppressive therapy or history of receiving chemotherapy in last 5 years other than topical agents; 5. Receipt of systemic glucocorticoids (a dose ≥ 20 mg/day prednisone or equivalent for 14 days) within 1 month, or any other cytotoxic or immunosuppressive drug within 6 months prior to injection of first dose; 6. Cancer diagnosis in the last 5 years, excluding basal cell and squamous cell carcinoma of the skin, which are allowed; 7. Presence of autoimmune disease; 8. Receipt of any investigational drug within 6 months; 9. Receipt of any non-COVID-19 authorized vaccines within 2 weeks of receiving study dose injection; 10. Receipt of any authorized COVID-19 vaccine prior to study enrollment; 11. Receipt of any other experimental SARS-CoV-2/COVID-19 or other experimental coronavirus vaccine(s) at any time prior to or during the study; 12. Receipt of blood products or immunoglobulin (IVIg or IMIg) within 3 months of study entry/baseline serologic evaluation; Adult: 19 Year-44 Year 18 Year(s) 54 Year(s) Both
