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):

1.-Quantification of specific anti-RBD IgG antibody titers (AU / mL). Measurement time: at 14 days after the administration of the dose with respect to the baseline. 2.-Percentage (%) of inhibition of the binding of the RBD protein to the ACE2 receptor in serum. Measurement time: on days 14 and 28 after the administration of the dose, and every 28 days until the decrease in titers.

Key secondary outcomes:

1.- Quantification of specific anti-RBD IgA antibody titers (AU / mL) in saliva and nasal discharge. Measurement time: baseline and on days 14 y 28 after the administration of the dose, and only in stage 1, every 28 days until titers decline. 2.- Title of neutralization of SARS-CoV-2. Measurement time: on days 14 and 28 after the administration of the dose, and every 28 days until the decrease in titers. 3.- Percentage (%) of seroconversion. Measurement time: on days 14 and 28 after the administration of the dose and every 28 days until the decrease in titers.
