- To evaluate the safety of a therapeutic Covid-19 vaccine in participants by measuring the severity of local and systemic adverse events and laboratory abnormalities. [ Time Frame: 26 weeks ]Frequency and severity of adverse events, laboratory abnormalities, local and systemic reactogenicity, signs and symptoms after vaccinations.
- To evaluate the immunogenicity of a therapeutic Covid-19 vaccine in participants by measuring CD8+ T cells immune response [ Time Frame: 6 weeks ]Magnitude of IFN-γ producing CD8+ T cells to SARS-CoV-2 nucleocapsid peptides pools after vaccinations.
- Virologic response after vaccination [ Time Frame: 4 weeks ]Detection of SARS-CoV-2 by RT-PCR in respiratory tract specimens at week 0, 1, 2, 3, and 4.
- Clinical outcome and progression after vaccinations [ Time Frame: 6 weeks ]Number of participants with moderate, severe or critical Covid-19 at week 6.

Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Documentation of Covid-19 infection based on laboratory evidence of positivity by RT- PCR.
- Patients who have no clinical symptoms (fever, cough and dyspnea).
- Patients who have mild clinical symptoms that could include fever, cough, sore throat, malaise, headache, muscle pain, gastrointestinal symptoms, without shortness of breath (dyspnea).
- Screening laboratory values within institutional normal range or judged to be not clinically significant by clinical investigator.
- Ability and willingness of subject to give written informed consent.
- Negative pregnancy test on the day prior to each vaccination.
- Willingness to use adequate contraception by study participants.
Exclusion Criteria:
- History of respiratory and cardiovascular diseases, hematologic disease (e.g., cryoglobulinemia, lymphoma), renal disease, dermatologic disease (e.g., lichen planus, porphyria cutanea tarda).
- Autoimmune diseases or clinically serious cardiac, pulmonary, gastrointestinal, hepatic, renal or neurologic disease, which in the opinion of the investigator will compromise ability to participate in the study.
- Pregnancy and breast-feeding.
- Prior or current systemic cancer chemotherapy.
- Investigational agents and immunomodulators (cyclosporine, hematological growth factors, systemic corticosteroids, interleukins or interferons) within 90 days prior to study entry.
- Anaphylaxis or allergy to vaccine components.
- Active drug or alcohol use or dependence that, in the opinion of the investigator, would interfere with adherence to study requirements.
- Any other serious diseases other than Covid-19 infection including current or recent (within 5 years) cancers.
- Subjects who are immunocompromised or immunosuppressed due to disease or medications.
- Women who are lactating.
