About
This is an Open-labeled, Randomized, Controlled Phase IV Clinical Trial to Evaluate the Immunogenicity and Safety of Booster Dose of Sabin Strain Inactivated Poliovirus Vaccine (Vero cell) (sIPV) Co-administered with Measles, Mumps, Rubella (MMR) Combined Live Attenuated Vaccine and Inactivated Hepatitis A (Hep-A) Vaccine.
Full description
The trial plans to enroll 960 infants aged 18 months (+4 months) who had completed three primary doses of sIPV vaccine and were assigned in a 2:2:2:1:1 ratio to four groups including trial group 1, trial group 2, control group 1, control group 2, control group 2, with informed consent from the participant's guardian. Trial group 1 receive one dose of sIPV co-administered with one dose of MMR vaccine. Trial group 2 receive one dose of sIPV co-administered with one dose of inactivated hepatitis A vaccine. Control group 1 receive one dose of sIPV, control group 2 receive one dose of MMR vaccine, and control group 3 receive one dose of inactivated hepatitis A vaccine. About 3.0 ml of venous blood will be collected from all participants before and 30 days after vaccination for antibody detection. Immediate reactions will be observed for 30 minutes after vaccination, and adverse events occured from 0 to day 30 after vaccination will be collected.
