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):

Percentage of serious adverse events related to the investigational product (Adverse events classified as serious with a causal association consistent with vaccination according to the Cuban vaccine pharmacovigilance system). Measurement time: up to 28 days after the third dose. 2. Proportion of subjects with seroconversion of SARS-CoV-2 anti-RBD IgG antibodies (Considering seroconversion as ≥ 4 times the initial determination of the antibody titer). Measurement time: day 56.

Key secondary outcomes:

Description of AE (name of event), -Intensity of AE (mild, moderate, severe), -Seriousness of adverse events (Serious, Not serious), -Causality relationship (causal association consistent with vaccination, Indeterminate, Inconsistent causal association with vaccination, not classifiable), - Result (Completely resolved, Resolved with sequelae, Conditions improving, Condition present and unchanged, Worsening, Death caused by this event)). Measurement time: 1, 24, 48 and 72 hours and, 7 days after the administration of each dose, 14 days after the administration of the 1st and the 2nd dose, respectively, and up to 28 days after the 3rd dose of the vaccine candidate. 2. Inhibition to ACE2 by ELISA. Measurement time: days 0 and 56. As a variable for exploration: 3. Percentage of SARS-CoV-2 viral neutralization response. Measurement time: Day 56. (Only 10% of those with ≥ 30% inhibition to ACE2 will be evaluated by ELISA at a 1/100 dilution of the sample).
