简要总结
This study is an open-label combined randomized double-blind, positive control phase Ⅰ clinical trial of the a 13-valent Pneumococcal Polysaccharide Conjugate Vaccine manufactured by Sinovac Research & Development Co., Ltd. The purpose of this study is to preliminary evaluate the safety and immunogenicity of the study vaccine
详细描述
This study is an open-label combined randomized double-blind, positive control phase Ⅰ clinical trial in subjects aged 2 months (minimum 6 weeks) and above. The experimental vaccine was manufactured by Sinovac Research \& Development Co., Ltd. .And one of the positive control vaccine was manufactured by WALVAX Biotechnology Co., Ltd( WALVAX PCV13) ,the other manufactured by Pfizer(Pfizer PCV13).A total of 310 subjects including 20 adults aged 18-49 years,20 adolescents and children aged 6\~7 years ,60 children aged 2-5 years,60 infants aged 12\~23 months,60 infants aged 7 \~11 months,60 infants aged 2 months (minimum 6 weeks), and 30 infants aged 3 months will be enrolled.Subjects will be assigned to receive one dose , two doses ,three doses or four doses of experimental vaccine or different positive control vaccines . Subjects aged 18-49 years will receive one dose of experimental vaccine.Subjects aged 6\~17 years will receive one dose of experimental vaccine.Subjects aged 2\~5 years will be randomly divided into two groups in a ratio of 1:1,and each group will receive one dose of experimental vaccine or control vaccine(WALVAX PCV13）.Subjects aged 7 \~ 11 months and subjects aged 12 \~23 months will be randomly divided into two groups in a 1:1 ratio,the subjects aged 12 \~ 23 months will receive two doses of experimental vaccine or control vaccine on the schedule of month 0,2 .Subjects aged 7 \~11 months will receive 3 doses of experimental vaccine or control vaccine (WALVAX PCV13）on the immunization schedule of month 0,2,4.Subjects aged 3 months will receive 4 doses of experimental vaccine.Subjects aged 2 months will be randomly divided into 2 groups in a 1:1 ratio and each group will receive 4 doses of experimental vaccine or control vaccine (Pfizer PCV13).
