Brief Summary

This is a phase I prospective, open-labeled, single-center study to evaluate the safety and immunogenicity of MVC-COV1901.

Detailed Description

This is a phase I prospective, open-labeled, single-center study to evaluate the safety and immunogenicity of MVC-COV1901. This study is a dose escalation study with three separate arms for subjects at the age of ≥20 and <50 years. The vaccination schedule for primary regimen consists of two doses of MVC-COV1901 for each study subject, administered by intramuscular (IM) injection 0.5mL in the deltoid region of non-dominant arm preferably 28 days apart, on Day 1 and Day 29. Subjects will receive a single booster vaccination of MVC-COV1901 on Day 209, 180 days after completion of the primary regimen.

• Have a negative pregnancy test

4. Subject is willing and able to comply with all required study visits and follow-up required by this protocol

5. Subject has no overseas travel within 14 days of screening and will not have any throughout the study period

6. Subject must provide written informed consent or the Subject's legal representative must understand and consent to the procedure

Exclusion Criteria

1. Receiving any investigational intervention either currently or within 30 days of first dose;

2. Subject (particularly who is a healthcare worker) with previous known or potential exposure to SARS CoV-1 or 2 viruses (EXCEPT for those who have been tested negative and the 14-days self-managements/ home quarantines/ home isolations are completed), or received any other COVID-19 vaccine;

3. Administration of any vaccine within 4 weeks of first dose;

4. A BMI greater than or equal to 30 kg/m2;

5. Subject with a history of hypersensitivity to any vaccine or a history of allergic disease or reactions likely to be exacerbated by any component of the MVC-COV1901;

6. Administration of any blood product or intravenous immunoglobulin administration within 12 weeks of first dose;

7. Pregnancy or breast feeding or have plans to become pregnant in 30 days after last injection of study vaccines;

8. History of positive serologic test for HIV, hepatitis B surface antigen (HBsAg) or any potentially communicable infectious disease as determined by the investigator or Medical Monitor;

9. Positive serologic test for hepatitis C (EXCEPTION: successful treatment with confirmation of sustained virologic response);

10. Baseline evidence of kidney disease as measured by creatinine greater than 1.5 mg/dL;

11. Screening laboratory tests with Grade 2 or higher abnormality (Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials, September 2007);

12. Immunosuppressive illness including hematologic malignancy, history of solid organ or bone marrow transplantation;

13. A history of autoimmune disease (systemic lupus, rheumatoid arthritis, scleroderma, polyarthritis, thyroiditis, etc.);

14. Current or anticipated concomitant immunosuppressive therapy (excluding inhaled, topical skin and/or eye drop-containing corticosteroids, low-dose methotrexate, or less than prednisone 20 mg/day or equivalent) within 12 weeks of first dose;
