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) Serious Adverse Events-SAE (It will measure as: -Occurrence of the SAE (Yes, No), - Duration (Time from start date until end date of event), -Description of the event, Result (Recovered, Recovered with squeals, Persists, Death, Unknown), - Causality (Causal association consistent with vaccination, Undetermined, Inconsistent causal association with vaccination, not classifiable). Measurement time: daily for 28 days after each dose.
Key secondary outcomes:
1) Solicited Local and systemic Adverse Events (AE) (They will measure as: -Occurrence of the AE (Yes, No), Duration (Time from start date until end date of event), -Intensity of the AE (mild, moderate, severe), -Severe (Serious, not serious), -Result (Recovered, Recovered with sequelae, Persists, Death, Unknown), -Causation (causal association consistent with vaccination, Indeterminate, causal association inconsistent with vaccination, not classifiable)). Measurement time: daily for 7 days after each dose.
2) Unsolicited Adverse Events (AE) (They will measure as: Description of the AE (name of the event), Duration (Time from start date until end date of event), -Intensity of the AE (mild, moderate, severe), -Severe (Serious, not serious) , -Result (Recovered, Recovered with sequelae, Persists, Death, Unknown), -Causality (causal association consistent with vaccination, Undetermined, causal association inconsistent with vaccination, not classifiable)). Measurement time: daily for 28 days after each dose .
3) Titer of specific anti-RBD IgG antibodies (Percentage of subjects with seroconversion 4 fold). Measurement time: Day 28, 42 and 56 for all groups and, day 84 for group 3, and 28 days after the booster dose for groups 1 y 2.
4) Neutralizing antibody titer: Measurement time: Day 0 and 56 for all groups and, day 84 for group 3, and 28 days after the booster dose for groups 1 y 2.
5)% ACE2-RBD inhibition: Measurement time: Day 0, 28, 42 and 56 for all groups and, day 84 for group 3, and 28 days after the booster dose for groups 1 y 2.
