Brief Summary:
This study evaluated the antibody persistence of Chinese children five years after they received four doses of sIPV, two doses of MMR vaccine and one dose of HepA-L vaccine.
Detailed Description:
This is a follow-up study of several previous clinical trials (A Randomized, Controlled, Multicenter Phase 4 Clinic Trial to Evaluate the Immunogenicity and Safety of Combined Immunization of Sabin-strain Inactivated Polio Vaccine (sIPV), Diphtheria, Tetanus, Pertussis Vaccine (DTaP) and Measles, Moms and Rubella Vaccine (MMR) : NCT04054882, NCT04638985; A Randomized, Controlled, Multicenter Phase 4 Clinic Trial to Evaluate the Safety and Immunogenicity of Combined Immunization of Sabin-strain Inactivated Polio Vaccine (sIPV), Diphtheria, Tetanus, Pertussis (DTaP) Vaccine and Live Attenuated Hepatitis A Vaccine (HepA): NCT04053010, NCT04636827). Five years after vaccination with sIPV, MMR or HepA-L, blood samples were collected from the followed-up children to assess the antibody levels and seropositive rates against polio, measles, rubella, mumps and hepatitis A. This study was conducted in six provinces of China.
