Active clinical trials for "Tetanus"

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.

The aim of the study is to assess the immunogenicity and safety profile of ADACEL compared to local adsorbed diphtheria and tetanus combined vaccine (local DT or local Td vaccine in participants in China. Primary objective: To describe diphtheria and tetanus seroprotection rates and pertussis booster response rates induced by each of the study vaccines: ADACEL vaccine (in all study age groups), local DT vaccine (in children), and local Td vaccine (in adolescents and adults). Secondary Objectives: To further describe in each group the immunogenicity of the study vaccines at baseline and 1 month after vaccination. To describe the safety of the study vaccines

The purpose of this study is to determine the effectiveness, safety and feasibility of a tetanus toxoid (TT) vaccination strategy relying on the maintenance of vaccines in a controlled temperature chain (CTC). The CTC is defined as the storage and transport of vaccines within a temperature range appropriate to the heat stability profile of TT vaccine. In this study vaccines are transported and stored in the cold chain up to district level. From district to beneficiary level vaccines are exposed to ambient temperatures during a limited period of time. In an initial phase, the stability of 3 lots of TT vaccine kept in CTC is determined. For this, the potency, safety, pH and adsorption of vaccines maintained in CTC will be tested in the laboratory and compared to vaccines that have been maintained in cold chain. If all parameters (i.e. potency, safety, pH and adsorption) are above WHO specifications the strategy in CTC will be used. Only if the laboratory results are adequate, villages will be assigned to one of the vaccination strategies. All women between 14 to 49 years of age in the selected villages who fulfill the inclusion criteria will be invited to participate. In order to determine the baseline anti-tetanus protection, TT vaccination history will be collected from all participants using a standardized questionnaire. Women who have already received at least 2 doses of TT vaccine will be excluded from the study. Moreover, blood will be collected from all participants to later verify in laboratory the baseline protection. A first dose of TT vaccine will be given according to the assigned strategy (CTC or cold chain). Four weeks after the 1st vaccination, a second TT vaccine will be given using the same strategy employed for the first dose. Finally, four weeks after the second dose, a blood sample will be collected from all participants who received two doses of vaccine. The serological responses will be compared in the group that received two doses of TT vaccine maintained in cold chain ant the group that received two doses of vaccine maintained in CTC.

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 describe immunogenicity of a single booster dose of Adacel vaccine versus Boostrix vaccine among approximately 420 adolescents 11 to <13 years of age. Primary objective: To describe seroprotection rates against tetanus and diphtheria in subjects randomized to receive either Adacel or Boostrix vaccine. Observational objectives: To describe pre- and post-vaccination tetanus, diphtheria, and pertussis geometric mean antibody concentrations (GMCs) in subjects randomized to receive either Adacel or Boostrix vaccine. To describe booster response rates against tetanus, diphtheria, and pertussis in subjects randomized to receive either Adacel or Boostrix vaccine. To describe the rates of adverse events (AEs) immediately post-vaccination, and the rates of unsolicited AEs and serious adverse events (SAEs) following vaccination with Adacel or Boostrix vaccine from Visit 1 through Visit 2.

The clinical trial is a phase III, double-blind, randomised, controlled, multi-centre, clinical trial, on the immunogenicity and safety of TdaP vaccine in comparison to Td vaccine when given as a booster vaccination to adults who were vaccinated with D, T and wP vaccine according to the Danish vaccination programme in their childhood. Healthy, adult, female or male volunteers, who completed primary vaccination with diphtheria (D), tetanus (T) and whole cell pertussis vaccine (wP), typically during their childhood, is the target population.

Objectives: To present the rates of adverse reactions after a dose of DAPTACEL® vaccine administered to children 4 to 6 years of age who have previously received four doses of PENTACEL™ vaccine. To present immunogenicity before and after a single dose of DAPTACEL® vaccine administered to children 4 to 6 years of age who have previously received four doses of PENTACEL™ vaccine.

The study aims to confirm that, in Peruvian infants, the investigational DTaP-IPV Hep B-PRP~T vaccine has immunological and safety profiles that are comparable to those of the control vaccine that is already marketed (Infanrix®Hexa) Primary Objective: To demonstrate that the hexavalent DTaP-IPV-Hep B-PRP~T combined vaccine induces an immune response that is at least as good as the response following Infanrix®Hexa in terms of seroprotection rates to HB, one month after a three-dose primary series (2, 4 and 6 months) Secondary Objectives: To describe in each group the immunogenicity to vaccine components (for DTaP-IPV-Hep B-PRP~T and Infanrix®Hexa) one month after the third dose of the primary series. To assess the overall safety in each group one month after each dose of the primary series and through the entire study.

To compare the seroprotection rates and booster responses to Canadian-manufactured Tetanus and Diphtheria Toxoids Adsorbed vaccine to the seroprotection rates and booster responses to the US-manufactured Tetanus and Diphtheria Toxoids Adsorbed vaccine when administered to subjects ≥ 60 years of age. To compare the post-vaccination geometric mean titers of antibody (GMTs) to Canadian manufactured Tetanus and Diphtheria Toxoids Adsorbed vaccine to the post-vaccination GMTs to the US manufactured Tetanus and Diphtheria Toxoids Adsorbed vaccine when administered to subjects ≥ 60 years of age.

DTaP-HB-PRP~T combined vaccine is being developed in order to comply with expanding programs for immunization in infancy, while offering the benefit of a reduced number of injections, and potentially of an increased acceptance. Primary Objectives: To describe the antibody persistence at 12 to 18 months following a three-dose primary series vaccination of either DTaP-HB-PRP~T or Tritanrix-Hep B/Hib™ given at 6, 10 and 14 weeks of age, and one dose of Hepatitis B (Hep B) vaccine given at birth. To describe the effect of a booster dose of DTaP-HB-PRP~T on immunogenicity at 12 to 18 months following a three-dose primary series vaccination of either DTaP-HB-PRP~T or Tritanrix HepB/Hib™ given at 6, 10 and 14 weeks of age, and one dose of Hep B vaccine given at birth. Secondary Objective: To describe the safety profile of the booster dose of the DTaP-HB-PRP~T vaccine when administered concomitantly with Oral Polio Vaccine (OPV).
