Exclusion criteria
Exclusion criteria: 1. Acute infectious disease at the time or within 7 days before the application of each dose. (You can wait up to 14 days after the date on which the second dose and booster dose vaccination is due). 2. Use of any investigational product. 3. Present a history of immunosuppressive or immunostimulant treatment in the 30 days prior to the administration of the vaccine. 4. History of treatment with blood products such as transfusions of blood cells, plasma, whole blood, platelet concentrate, gamma globulins and transfer factor at some point in their life. 5.

Infants with a history of receiving any vaccine from the Cuban vaccination scheme in a period of less than 15 days, prior to the administration of the investigational product.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Seroprotection (It is defined as concentration of anti-PsC IgG antibodies = 0.35 µg/mL [= 0.35 /< 0.35]). Measurement time: Four weeks after second dose and, four weeks after booster dose. 2. Adverse Events-AE (Type of AE (Description of the AE), Severity of the AE (Grievous/Serious; Not grievous/Not serious), Intensity of the AE (Mild, Moderate, Severe), Causality of the AE (A. Causal association consistent with immunization [A1. Event related to the vaccine product; A2. Event related to a vaccine quality defect; A3. Event related to immunization errors; A4. Event related with immunization anxiety]; B. Undetermined [B1. The temporal relationship is consistent, but there is insufficient definitive evidence that the vaccine caused the event; B2. Review of factors results in conflicting trends of consistency - inconsistency of causal association with immunization]; C. Inconsistent causal association with immunization; D. Not classifiable)). Measurement time: until four weeks after booster dose. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Antibody concentration (Concentration of anti-Psc IgG antibodies [ug/ml]). Measurement time: Four weeks after second dose and, four weeks after booster dose. 2. Opsonophagocytic titers (Functionality of the antibodies determined through opsonophagocytic titers in a subsample of 20% of the included participants; titers = 1:8 will be considered protection according to the correlation of protection established by the WHO). Measurement time: Four weeks after booster dose. 3. Opsonophagocytic titers = 1:8 (Opsonophagocytic titers = 1:8/Opsonophagocytic titers < 1:8). Measurement time: Four weeks after booster dose. | — |
