Summary
Streptococcus pneumoniae is a major cause of morbidity and mortality in children worldwide, resulting in up to 1 million pediatric deaths every year. Since the licensure of PCV7, PCV10, PCV13 and PCV15, the reported overall decline in invasive pneumococcal disease in hospitalized children younger than 5 years is approximately 60% around the world. This is a single center, blinded, randomized, positive-controlled phase I clinical trial to evaluate the safety and explore the immunogenicity of a candidate PCV13 in healthy people aged 2 months (minimum 6 weeks) and above.
