Active clinical trials for "Diphtheria"

Diphtheria, tetanus and pertussis are common causes of diseases worldwide, with significant morbidity and mortality. The purpose of this study is to assess the immunogenicity, safety and reactogenicity of a single dose of GlaxoSmithKline (GSK) Biologicals' Boostrix vaccine, administered as a booster dose in healthy Russian subjects. An equal number of subjects are expected to be recruited in the following age categories: 4-9 years (children), 10-17 years (adolescents), 18-64 years (adults) and ≥65 years (elderly population). By receiving the Boostrix vaccine, the subjects could be protected against diphtheria, tetanus and pertussis diseases.

The purpose of this study is to assess the immunogenicity and safety of the Infanrix hexa booster dose given at 11-18 months of age to infants who received primary vaccination at 6-14 weeks. All infants in this booster study were born to pregnant women who participated in the study 116945 [DTPA (BOOSTRIX)-047] and having received the full primary vaccination series as per protocol requirement in study 201330 [DTPA (BOOSTRIX)-048.

Faced with high rates of immunization drop-out, Uganda's immunization program requires innovative approaches to address this weakness. Building upon Uganda's growing mHealth infrastructure to pilot a scalable short message service (SMS) system to remind caregivers of their children's upcoming vaccination visits, it was hypothesized that the SMS intervention will increase immunization coverage in a cost-effective and affordable manner that would make it scalable. The study design was an investigator-blinded, multi-center, parallel groups randomized controlled trial with randomization occurring at the caregiver level in select health facilities of Arua District in Uganda. Enrollment took place at the time of Pentavalent 1 vaccination, and both arms included standard of care provided by the health worker. However, in the intervention arm, caregivers also received SMS text messages reminding them to return for their children's second and third doses of Pentavalent vaccine (four and eight weeks after the first dose of Pentavalent vaccine) and measles-containing vaccine (9 months of age). The primary outcome of interest is vaccination coverage at 12 months of age among children enrolled in the study and will be measured by comparing Penta3 and MCV coverage between arms. The study will also examine the SMS impact on timeliness of vaccine receipt, as it is hypothesized that those children receiving the SMS intervention will be more likely to have timely vaccination than those in the control group. The study will also assess caregiver acceptability and cost-effectiveness of the SMS intervention. In addition to assessing its impact on strengthening the immunization program, this intervention has implications for strengthening other programs of the health system through similar health messaging directed toward caregivers.

The objective of this study is to evaluate safety and tolerability of Diphtheria, Tetanus, Pertussis, Hepatitis B and Haemophilus influenzae type b Conjugate Vaccine Adsorbed in Vietnamese infants aged 6-12 weeks. This is an open label, single group, bridging study.

Pertussis, diphtheria and tetanus are seriously infectious diseases in children. Since using of the vaccine targeted the three components, it greatly reduced incidence of the three kinds of diseases. The Purpose of this study is to preliminary evaluate the safety of DTcP compared to adsorbed diphtheria and tetanus combined vaccine （DT），Diphtheria-tetanus-acellular pertussis vaccine（DTaP） or PENTAXIM（DTaP-IPV-Hib） in participants.

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 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.

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.

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.
