Brief 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 and PCV13,the reported overall decline in invasive pneumococcal disease in hospitalized children younger than 5 years several years is approximately 60% in Western countries.This is a single center,blind, randomized, positive-controlled clinical trial.The purpose of this study is to preliminary evaluate the safety of PCV13i vaccine in subjects at age of 7 months and above,and to investigate the safety and immunogenicity of PCV13i vaccine at age of 2 and 3 months,compared to PCV13.
