简要总结
The purpose of this study is to evaluate immunogenicity by measuring the seroprotection rate against diphtheria and tetanus at 28 days after vaccination with BR-TD-1001 and Td-pur-inj.
详细描述
Primary objective:
To evaluate immunogenicity by measuring the seroprotection rate against diphtheria and tetanus at 28 days after vaccination with BR-TD-1001 and Td-pur-inj.
Secondary objectives:
- To evaluate immunogenicity by measuring the geometric mean titer (of diphtheria and tetanus antitoxins at 28 days after vaccination with BR-TD-1001 and Td-pur-inj.
- To evaluate a boosting response by comparing before and after the administration through measurement of diphtheria and tetanus antitoxin titers at 28 days after vaccination with BR-TD-1001 and Td-pur-inj.
- To evaluate safety by observing solicited local and systemic adverse events that have occurred for 7 days after vaccination with BR-TD-1001 and Td-pur-inj.
- To evaluate safety by observing unsolicited adverse events that have occurred for 28 days after vaccination with BR-TD-1001 and Td-pur-inj.
