The purpose of this study is to evaluate the safety and immunogenicity of concomitant administration of EV71 vaccine with recombinant hepatitis B vaccine/Group A meningococcal polysaccharide vaccine.
This study is an open-label, single-center, randomized, comparative phase IV clinical trial. The purpose of this study is to evaluate the safety and immunogenicity of concomitant administration of EV71 vaccine manufactured by Sinovac (Beijing) Vaccine Technology Co., Ltd. with recombinant hepatitis B vaccine/Group A meningococcal polysaccharide vaccine. 780 healthy infants of 6 months old as participants are randomly assigned into three experimental groups in the ratio 1:1:1. The group I receive EV71 Vaccine (first dose)& recombinant hepatitis B vaccine on day 0 and EV71 vaccine (second dose)& Group A meningococcal polysaccharide vaccine on day 30. The group II receive recombinant hepatitis B vaccine on day 0 and Group A meningococcal polysaccharide vaccine on day 30. The group III receive the first and second dose of EV71 Vaccine on day 0 and day 30 respectively.

Biological Concomitant administration of EV71 vaccine with EPI vaccines [ev71 vaccine, hepatitis b vaccine (recombinant) (recombivax)]

The investigated EV17 vaccine was manufactured by Sinovac Biotech Co., Ltd.; the recombinant hepatitis B vaccine was manufactured by Shenzhen Kangtai Biological Products Co., Ltd; the Group A meningococcal polysaccharide vaccine was manufactured by Wuhan Institute of Biological Products Co., Ltd. The primary vaccination schedule of hepatitis B vaccine includes 3 doses with a schedule of 0,1,6 month, and subjects only receive 3rd vaccination in this study; the primary vaccination schedule of Group A meningococcal polysaccharide vaccine includes 2 doses with 3 months interval between doses, and subjects only receive 1st vaccination in this study

Biological Single injection of EPI vaccine

The primary vaccination schedule of hepatitis B vaccine includes 3 doses with a schedule of 0,1,6 month, and subjects only receive 3rd vaccination in this study; the primary vaccination schedule of Group A meningococcal polysaccharide vaccine includes 2 doses with 3 months interval between doses, and subjects only receive 1st vaccination in this study

Biological EV71 Vaccine only

The investigated EV17 vaccine was manufactured by Sinovac Biotech Co., Ltd.

Group I-EV71 vaccine and EPI vaccines Experimental

Concomitant administration of EV71 vaccine with EPI vaccines: EV71 Vaccine (intramuscular injection,0.5ml,first dose)/recombinant hepatitis B vaccine(intramuscular injection,0.5ml)on day 0 and EV71 Vaccine (injection, 0.5ml,second dose)/ Group A meningococcal polysaccharide vaccine(subcutaneous injection, 150ug) on day 30.

Group II-EPI vaccine only Active Comparator

Single injection of EPI vaccine: recombinant hepatitis B vaccine (intramuscular injection, 0.5ml) on day 0 and Group A meningococcal polysaccharide vaccine (subcutaneous injection,150ug) on day 30.

Group III-EV71 vaccine only Active Comparator

EV71 Vaccine only: the first and second dose of EV71 Vaccine (intramuscular injection,0.5ml) on day 0 and day 30 respectively.
