Health condition and Intervention

Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Health condition(s) or Problem(s) studied:

Pneumococcal diseases

Intervention(s):

Elevenvalent Conjugate Vaccine against Pneumococci (PCV11) (Experimental group): The vaccine will be administered by intramuscular route on the anterolateral aspect of the left thigh. Primary vaccination - Two doses with an interval of 8 weeks (First dose at 2 months of age and second dose at 4 months of age). Single booster dose, at 11 months of age Prevnar13® vaccine, from Pfizer (Control group): The vaccine will be administered by intramuscular route on the anterolateral aspect of the left thigh. Primary vaccination - Two doses with an interval of 8 weeks (First dose at 2 months of age and second dose at 4 months of age). Single booster dose, at 11 months of age

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. 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.

Key secondary outcomes:

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.
