Active clinical trials for "Poliomyelitis"

The purpose of this phase III study is to evaluate the immunogenicity and safety of Sabin Inactivated Poliovirus Vaccine (Vero cell) in 2-month-old infants.

This study is to evaluate the immunogenicity and safety of Sabin IPV or bOPV, given as a booster vaccination in children aged 4 years who were previously immunised with different sequential immunization history by Sabin IPV and bOPV, and to observe the antibody persistence three years after different primary sequential immunization with Sabin IPV or bOPV at age 2, 3 and 4 months.

The purpose of this study is to describe the immunogenicity and safety of a novel DTaP- IPV- Hep B-PRT~T fully liquid combined hexavalent vaccine (Hexaxim™) administered at 6, 10 and 14 weeks of age in infants born to mothers documented to be serum anti-hepatitis B surface antigen (HBsAg) serology negative in India. Primary Objective: To evaluate the immunogenicity of the study vaccine in terms of seroprotection [diphtheria toxoid, tetanus toxoid, poliovirus types 1, 2 and 3, Haemophilus influenzae type b (Hib) polysaccharide (PRP), hepatitis B (Hep B)] and vaccine response for pertussis antigens [pertussis toxoid (PT) and filamentous haemagglutinin (FHA)] one month after the third dose. Secondary Objectives: To further describe the immunogenicity of the study vaccine, before the first dose and one month after the third dose. To describe the safety after each and any doses of the study vaccine.

This study is a Phase IV, open, randomized, multi-center, controlled vaccine trial conducted in healthy Latin American infants, utilizing one or two supplemental doses of IPV in children previously vaccinated with 3 doses of bOPV. We will examine the impact of supplemental IPV on stool shedding and humoral immunity, as well as intra-IPV manufacturer comparability, and safety.

Primary objective: To determine the safety and immunogenicity of tetanus and diphtheria toxoids adsorbed combined with component pertussis and inactivated poliomyelitis vaccine grown on vero cells (TdcP-IPV) compared to tetanus and diphtheria toxoids adsorbed combined with component pertussis and inactivated poliomyelitis vaccine grown on vero cells (TdcP-IPV) and Hepatitis B vaccine administered concurrently in adolescents 11-14 years of age. Secondary objective: To determine whether concurrent administration of TdcP-IPV and Hepatitis B vaccines at 11-14 years of age results in detectable immunologic interactions between components of the two vaccines.

Global eradication of poliomyelitis has proven to be elusive. Although 99% of cases have been eliminated since 1988, outbreaks continue to occur, and new tools are needed to accelerate eradication. One concern in this effort is that some populations have decreased immunogenicity to oral poliovirus vaccine (OPV). Past studies have shown decreased seroimmunity to trivalent OPV (tOPV) in children with diarrhea. In 2009, bivalent OPV (bOPV) was recommended for use in immunization campaigns, and will likely replace tOPV in routine immunization in 2016. However, the effect of diarrhea on seroconversion to bOPV has not been studied. This project evaluated the effect of diarrhea on seroconversion to bOPV among infants who reside in Nepal. The investigators conducted a prospective, interventional study that assessed immune response to bOPV among infants with and without diarrhea. Immune responses were compared among infants with and without diarrhea. This study will result in a better understanding of the factors that decrease the ability of some children to seroconvert to OPV and be protected from poliomyelitis infection.

This study aims to evaluate the safety and reactogenicity of a booster dose of Infanrix-IPV+Hib™ when administered to healthy Vietnamese toddlers at 12 to 24 months of age who were vaccinated previously against diphtheria, tetanus, and pertussis diseases within their first six months of lives.

The aim of this study is to evaluate the immunogenicity and safety of a novel DTaP-IPV-Hep B-PRP~T fully liquid combined hexavalent vaccine (study vaccine) administered at 2, 4, and 6 months of age compared to Sanofi Pasteur's DTaP-IPV//PRP~T combined vaccine (Pentaxim™) given at 2, 4, and 6 months of age and Hep B vaccine (Euvax B®) given at 1 and 6 months of age in South Korean infants that received a birth dose of Hep B and born to mothers documented to be serum anti-HBs Ag negative. Primary Objective To demonstrate the non-inferiority in terms of seroprotection (Diphtheria, Tetanus, poliovirus types 1, 2, and 3, PRP-T, Hep B) and vaccine response for pertussis antigens (pertussis toxoid [PT] and filamentous haemagglutinin [FHA]) of Group A versus Group B, one month after the third dose of combined vaccines. Secondary Objectives: To further study the immunogenicity of the two vaccination schemes, before the first dose and one month after the last dose of vaccines. To study the safety after each and any dose of vaccines administered in the two vaccination schemes

The purpose of this study is to generate data to support the registration extension of IMOVAX Polio to be used in a sequential vaccination. Primary objective: To demonstrate the non-inferiority of Inactivated Poliomyelitis Vaccine (IPV)-(Oral Poliomyelitis Vaccine) (OPV)-OPV (Sequential 1) and IPV-IPV-OPV (sequential 2) poliovirus vaccine administrations versus OPV-OPV-OPV (Reference) in terms of seroprotection rate 28 to 42 days after the third dose of the primary vaccination series. Secondary objectives: To evaluate the safety profile of the investigational vaccines after each administration in each group. To describe the humoral immune response to poliovirus serotypes (types 1, 2 and 3) before the first dose and 28 to 42 days after the third primary series dose of vaccine in each group. To describe the persistence of antibodies against poliovirus serotypes (types 1, 2 and 3) after the third primary series dose administration, at 18 months of age in each group.

The aim of the study is to assess the immunogenicity and safety of SP059 as a three-dose primary and booster vaccination in Japanese infants aged 3 through 68 months. Primary objective: To assess that the seroprotection rates against polio types 1, 2 and 3 are over 90% approximately one month following the three dose primary vaccination series with inactivated polio vaccine (IPV). Secondary objective: To describe the immunogenicity (in terms of seroprotection / seroconversion vaccine response rates and Geometric Mean Titers) of IPV before and after the primary vaccination and before and after the booster vaccination. To describe the safety after each dose of IPV.
