- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: NONE

Immunosuppressive therapies will be considered: antineoplastic chemotherapy, radiation therapy, immunosuppressants to induce tolerance to transplants, among others.~* Have received an immunosuppressive dose of corticosteroids in the last three months before inclusion in the study or scheduled administration of an immunosuppressive dose of corticosteroids for the three months following inclusion in the study. The dose of corticosteroids considered immunosuppressive is equivalent to prednisone at a dose of 20 mg/day for adults for more than a week. The continuous use of topical or nasal corticosteroids is not considered immunosuppressive.~* History of asplenia, either anatomic or functional.~* History of bleeding disorders, as deficiency of clotting factors, coagulopathy, platelet dysfunction, or previous history of bleeding or significant bruising after IM injection or venipuncture.~* Any alcohol or drug abuse in the last 12 months before inclusion in the study that has caused medical, professional, or family problems, as indicated by clinical history.~* Have received blood products (transfusions or immunoglobulins) in the last three months before inclusion in the study.~* Have received any vaccine with a live attenuated virus in the last 28 days or inactivated vaccine in the last 14 days before their inclusion in the study, or have immunization scheduled for the first 28 days after their inclusion in the study.~* Participation in another clinical trial with product administration under investigation during the six months before its inclusion in the study or scheduled participation in another clinical trial in the two years following inclusion.~* Previous participation in a COVID-19 vaccine evaluation study or previous exposure to a COVID-19 vaccine.~* Fever (\>37.8°C) within 72 hours before vaccination.~* Any other condition that, in the opinion of the principal investigator or his medical representative, could jeopardize the safety or rights of a potential participant or that would prevent him from complying with this protocol.
