Study Arms (2)
SARS-COV-2 Vaccine
EXPERIMENTAL600 SU of SARS-CoV-2 virus antigen, intramuscular injection, two doses given 14 days apart.
Placebo
PLACEBO COMPARATORAluminium hydroxide, disodium hydrogen phosphate, sodium dihydrogen phosphate, sodium chloride 0.5mL/dose, intramuscular injection, two doses given 14 days apart.

Aluminium hydroxide, disodium hydrogen phosphate, sodium dihydrogen phosphate, sodium chloride 0.5mL/dose, two doses given 14 days apart.
Eligibility Criteria
You may qualify if:
- years of age (including 18 and 59 years of ages),
- For only K1 cohort, health care workers such as medical doctor, nurse, ward boy, cleaner, hospital technician, administrative personnel who work in any department of a hospital.
- Signed informed consent
You may not qualify if:
- Previously PCR positive for COVID-19
- IgG or IgM is positive
- For females: Pregnancy (confirmed by positive beta-hCG test), breastfeeding or intent to engage in sexual relations with reproductive intent without use of birth control methods in the three months following vaccination
- Known allergy to components of the study vaccine or control
- Use of immunosuppressant therapy regimens within the six months prior to enrollment in the study or planned use within the two years following enrollment. Immunosuppressant therapy regimens include: antineoplastic chemotherapy, radiation therapy and immunosuppressants to induce transplant tolerance, among others
- Use of immunosuppressive doses of corticosteroids within the three months prior to the enrollment in the study and planned use of immunosuppressive doses of corticoids within the three months following enrollment in the study. Immunosuppressive doses of corticosteroids will be considered the equivalent prednisone 20 mg/day for adults, for longer than one week. Continued use of topical or nasal corticosteroids is not considered an immunosuppressant
- History of asplenia
- History of bleeding disorder (e.g. factor deficiency, coagulopathy or platelet disorder), or prior history of significant bleeding or bruising following IM injections or venipuncture
- Any alcohol or drug abuse over the 12 months prior to enrollment in the study that has caused medical, professional or family problems, indicated by clinical history
- Administration of immunoglobulins and/or any blood products within the three months preceding the planned administration of the vaccine candidate
- Participation in another clinical trial with an investigational product in the six months prior to enrollment in the study or planned participation in another clinical trial within the two years following enrollment
- Received live attenuated virus vaccine 14 days prior to enrollment in the study
- Inactivated vaccine or sub unit vaccine 7 days prior to enrollment in the study
- Fever (oral temperature \>37.2℃, axillary temperature will not be accepted) within the past 24 hours
- Any other condition that, in the opinion of the principal investigator or his/her representative physician, could put the safety/rights of potential participants at risk or prevent them from complying with this protocol.
