Clinical Trial Summary

This study is to evaluate the immunogenicity and safety of DTaP or DT given in children aged 6 years.


Clinical Trial Description

A phase 4 trial was conducted in Zhejiang Province aimed to evaluate the immunogenicity and safety of DTaP or DT in children aged 6 years. DTaP and DT are produced by Wuhan Biological Products Co., LTD. Participants will be recruited and randomly divided into two groups to receive DTaP or DT in 1:1 ratio. Two blood samples were taken on Day 0 (pre-vaccination) and Day 28~42 (after-vaccination) for test antibody against pertussis, diphtheria and tetanus. Adverse events and serious adverse events were actively collected by staff within 28 days of vaccination. ;
