Active clinical trials for "Poliomyelitis"

The purpose of this study is to assess the safety (serious adverse events [SAEs]), and severe adverse events [AEs] (grade 3 according to CTCAE 4.03) after one dose of SABIN tOPV in 1-5 year-old children and three doses of SABIN tOPV in 6 week-old infants, and immunogenicity (seroprotection rates for all 3 serotypes) 28 days after three doses of SABIN tOPV in vaccine-naïve infants.

Type 2 component of oral poliovirus vaccine is slated for global withdrawal through a switch from trivalent oral poliovirus vaccine (tOPV) to bivalent oral poliovirus vaccine (bOPV) for preventing paralytic polio caused by circulating vaccine-derived poliovirus type 2. We aimed to assess immunogenicity and safety profile of six vaccination schedules with different sequential doses of inactivated poliovirus vaccine (IPV), tOPV, or bOPV.

The purpose of this study is to describe the immunogenicity and safety of Sanofi Pasteur's DTaP-IPV-Hep B-PRP-T fully liquid combined hexavalent vaccine (Hexaxim®) administered at 2, 3, and 4 months of age and at 16 to 17 months of age in infants and toddlers who received a dose of Hep B vaccine at birth or within 1 week after birth. Primary Objective: To describe the safety profile after each and all doses of Sanofi-Pasteur's DTaP-IPV-Hep B-PRP-T combined vaccine in Vietnamese infants and toddlers. Secondary Objective: To demonstrate the non-inferiority of the immune response to all antigens induced by the study vaccine in Vietnamese infants one month after the third dose in a 3-dose primary series with the immune response to all antigens induced by the same study vaccine outside Vietnam. To evaluate the immunogenicity of the study vaccine one month after the 3-dose primary series. To describe the persistence of all antibodies before receipt of the booster vaccination. To evaluate the immunogenicity of the study vaccine one month after the booster.

The purpose of this study is to investigate if the study vaccine, m-IPV2 HD (vaccine that only contains polio serotype 2 in high dose), is as safe as the standard IPV Imovax (that contains the 3 serotypes of polio). This safety evaluation will be done in young adults. If the study vaccine appears to be safe, it will be tested at a later stage in the target group (infants and children) to evaluate the immunogenicity of the vaccine. After all, the purpose is to use the study vaccine in the future to protect young children against Polio serotype 2. Disease with Polio type 2 indeed recently re-appeared, so vaccination of young children to come to a complete eradication of Polio is needed. The standard use of Imovax to protect against Polio serotype 2 would be too expensive. Therefore, a monovalent Polio vaccine containing only serotype 2 (= the vaccine that will be evaluated in this study), has been developed. The duration of the study will be approximately 6 months. 120 subjects between 18 and 45 years of age will participate in Belgium. During the study there will be 2 groups of subjects. Subjects will be assigned by chance to one of these groups. One group will receive one single injection of the study vaccine m-IPV2 HD (which contains only serotype 2), the other group will receive one single injection of the standard polio vaccine IPV, Imovax (which contains the 3 serotypes). After this vaccination, there will be a follow-up period of 6 months. Subjects will be asked to come to the study centre one more time for the second visit (on Day 8, which is 7 days after the first visit). They will also receive 2 follow-up phone calls for approximately one month and 6 months after vaccination.

The purpose of this study is to assess the immunogenicity and safety of GSK Biologicals' Infanrix hexa vaccine when administered to healthy infants as primary vaccination at 2, 4 and 6 months of age, co-administered with Prevnar and Rotarix with a booster dose of GSK Biologicals' Infanrix and Hiberix vaccines at 15-18 months of age.

Bilthoven Biologicals has developed a new bivalent oral polio vaccine (bOPV) containing World Health Organization (WHO) approved Sabin strains of poliovirus type 1 and type 3. This study will assess non-inferiority of bOPV manufactured by BBio to that of licensed bOPV. This study will also assess lot-to-lot consistency among three lots of BBio bOPV.

Primary objective: To demonstrate the non-inferiority in terms of seroprotection rates (Hib antigen (PRP), Diphtheria, Tetanus, and Pertussis antigens (PT and FHA), and polio types 1, 2 and 3 antigens) of investigational arm (Group A: DTaP-IPV/Hib) versus control arm (Group B: DTaP-IPV and Hib vaccines administered at separate sites), one month after the primary vaccination (all antigens). Secondary objectives: To describe immune responses against all vaccine antigens with no pre-specified hypothesis, and at all time points (pre-dose 1, post-dose 3, pre-dose 4 and post-dose 4) in the two study groups (Group A and Group B). To describe the safety after each dose of each vaccine in the two study groups (Group A and Group B). To describe immune responses against all vaccine antigens with no pre-specified hypothesis, and at all time points (pre-dose 1, post-dose 3, pre-dose 4 and post-dose 4 (Group C)

The current trial will evaluate the safety and immunogenicity of GSK Biologicals' GSK2202083A vaccine when administered as a booster dose following priming in the first year of life with the same vaccine. This protocol posting deals with objectives & outcome measures of the booster phase. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00970307).

This study is designed to assess the immunogenicity and safety of PENTAXIM™ combined vaccine versus TETRAXIM™ vaccine to support registration of PENTAXIM™ in South Korea. Primary Objective: To demonstrate the non-inferiority in terms of seroprotection rates (Diphtheria, Tetanus, Polio types 1, 2 and 3, Polyribosyl Ribitol Phosphate [PRP]) and vaccine response rates to acellular Pertussis antigens of sanofi pasteur's PENTAXIM™ vaccine versus sanofi pasteur's TETRAXIM™ and Act (Haemophilus influenzae type b) HIB™ vaccines, one month after the three-dose primary vaccination.

The study will compare the immunogenicity and the reactogenicity of INFANRIX™ HEXA and HEXAVAC™ vaccines in a 3, 5 and 11 - 12 month vaccination schedule.
