简要总结

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

详细描述

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.
