简要总结
In order to evaluate immunogenicity and safety of a 13-valent pneumococcal conjugate vaccine produced by Beijing Minhai Biotechnology Co., Ltd., a randomized, double-blind, parallel-controlled phase III clinical trial is planned to conduct in healthy infants aged 2 months in China.
详细描述
There will be two arms. 1200 healthy infants aged 2 months will be randomly assigned (1:1) to receive an experimental vaccine or a comparator vaccine in Month 0,2 and 4 (primary vaccination). All of them will receive a fourth dose as booster vaccination in Month 10.
