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):

Difference in geometric means of SARS-CoV-2 anti-RBD IgG antibody titers (numerical value). Measurement time: on days 0 and 14 (+ 3 days).

Key secondary outcomes:

1) Anti-RBD IgG antibody titers of SARS-CoV-2 at the time of application of the corresponding booster dose (numerical value). Measurement time: At baseline. 2) Percentage of individuals with inhibition of the interaction of RBD with its ACE2 receptor ≥ 30% in a subgroup of individuals (by ELISA - Assay by enzyme-linked immunosorbent). Measurement time: on days 0 and 14 (+ 3 days). 3) IgA antibody response in serum and nasal discharge in a patient’s subset (values according to sample type). Measurement time: on days 0 and 14 (+ 3 days). 4) 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), -Relation of causality (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: At the next 30 minutes after the vaccine was applied and, after 14 days (with review of the ambulatory card of adverse events, in the possession of each participant).
