Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Vaccine efficacy (Number of symptomatic COVID-19 subjects with no evidence of previous exposure to viral infection): Those subjects with SARS-CoV-2 positive RT-PCR who present at least one major symptom or sign will pay tribute to the efficacy evaluation or at least two of the minor symptoms or signs of COVID-19. Measurement time: from 14 days after the 3rd dose of the research product.

Key secondary outcomes:

1) Prevention of mild, moderate and severe forms of COVID-19 (number of symptomatic COVID-19 subjects according to intensity and evolution): Measurement time: from 14 days after the 3rd dose of the research product. 2) Prevention of asymptomatic cases in individuals confirmed by SARS-Co-V-2 PCR (number of SARS-CoV-2 PCR-positive subjects evolving asymptomatically). Measurement time: from 14 days after the 3rd dose of the research product. 3) Safety - Adverse clinical events-AE (They will be measured as: -Occurrence of AE (Yes, No), -Description of AE (name of event), -Intensity of AE (mild, moderate, severe), -Causality relationship (unrelated, doubtful, possible, probable, definitive), -Measures taken (None, Administration of any pharmacological therapy, Addition of a non-pharmacological therapy, Study exit, Hospitalization / prolongation of hospitalization), -Result (Completely resolved, Resolved with sequels, Conditions in improvement, Condition present and unchanged, Worsening, Death caused by this event)). Measurement time: before the administration of each dose of the research product, in the first hour after inoculation of the product (in each dose), and in the first 72 hours in active research in the community. 4) Proportion of subjects with seroconversion of SARS-CoV-2 anti-RBD IgG antibodies (seroconversion will be considered as that ≥ 4 times the initial determination of the antibody titer). Measurement time: at 56 ± 5 days with respect to baseline time. 5) Specific anti-RBD IgG antibodies (geometric mean). Measurement time: at 56 ± 5 days with respect to baseline time. 6) Inhibition to ACE2 (by ELISA - Enzyme Linked Immunoadsorption Assay). Measurement time: at 56 ± 5 days with respect to baseline time. 7) SARS-CoV-2 viral neutralization response percentage (only those samples that have ≥ 50% inhibition at a 1/100 dilution in the RBD-ACE-2 binding neutralization assay will be evaluated). Measurement time: at 56 ± 5 days with respect to baseline time.
