Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Other - Prevenar13
Treatment: Other - Synflorix

Experimental: Prevenar13 - The booster dose of Prevenar13 is 0.5 mL given intramuscularly only, with care to avoid injection into or near nerves and blood vessels. The preferred sites are anterolateral aspect of the thigh (vastus lateralis muscle) in infants or the deltoid muscle of the upper arm in young children.

Experimental: Synflorix - The booster vaccination schedule consists of one dose of 0.5 ml with an interval of at least 1 month between doses.


Treatment: Other: 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).

Treatment: Other: 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.
