Description of intervention(s) / exposure
Treatment: Drugs - Synflorix
Treatment: Drugs - Prevenar13
Treatment: Drugs - COMBO

Active comparator: Synflorix -

Active comparator: Prevenar13 -

Experimental: COMBO - COMBINATION SCHEDULE of comparator vaccine 1 and comparator vaccine 2 Synflorix at 1,2,4 months then Prevenar13 at 6 months.


Treatment: Drugs: Synflorix
The 10-valent vaccine contains 1 µg of purified capsular polysaccharide of pneumococcal serotypes 1, 5, 6B, 7F, 9V, 14, and 23F conjugated to protein D, 3 µg of serotype 4 conjugated to protein D, 3 µg of serotype 18C conjugated to tetanus toxoid and 3 µg of serotype 19F conjugated to diphtheria toxoid.

Treatment: Drugs: Prevenar13
The vaccine is a ready to use homogeneous white suspension for intramuscular injection, supplied as a pre-filled syringe.

Active ingredients

Each 0.5 mL dose contains:

2.2 µg of pneumococcal purified capsular polysaccharides for serotypes 1, 3, 4, 5, 6A, 7F, 9V, 14, 18C, 19A, 19F and 23F 4.4 µg of pneumococcal purified capsular polysaccharides for serotype 6B. Each serotype is individually conjugated to non-toxic diphtheria CRM197 protein and adsorbed on aluminium phosphate (0.565 mg). CRM197 is a nontoxic variant of diphtheria toxin isolated from cultures of Corynebacterium diphtheriae strain C7 (ß197) grown in a casamino acids and yeast extract-based medium.

Treatment: Drugs: COMBO
COMBINATION SCHEDULE of vaccine 1 and vaccine 2: Synflorix (PHiD-CV) at 1,2,4 months then Prevenar13 (PCV13) at 6 months of age.
