Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The research objective is to evaluate lot-to-lot consistency and immune persistence of three commercial batches of 23 valent pneumococcal polysaccharide vaccine.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study adopted a randomized, double-blind, equivalency design with different batches of experimental vaccine. 990 individuals aged 18-59 were included and divided into three groups at a ratio of 1:1:1, with 330 individuals in each group receiving three batches of experimental vaccines, respectively. All subjects were vaccinated with 1 dose of 0.5ml, intramuscularly injected into the lateral deltoid muscle of the upper arm.
