Active clinical trials for "Haemophilus Infections"

The main goal of this study is to compare the Haemophilus influenzae type b antibody response in American Indian / Alaska Native (AI/AN) infants to two licensed vaccines: Vaxelis and PedvaxHIB.

This is a single-center, randomized, active-controlled, parallel-design, double-blind, phase I study to evaluate the safety and immunogenicity of a single dose of APV006 in healthy adults.

The purpose of this study is to evaluate immunogenicity and safety of different doses of candidate hexavalent vaccine in comparison to co-administration of Pentavalent vaccine and Poliomyelitis Vaccine (Inactivated) in separate injections at four weeks after completion of three-dose primary series at 6-10-14 weeks of age when administered to healthy infants and thereby to select the optimal dose of candidate vaccine(Stage 1) and to demonstrate lot-to-lot consistency of three lots of LBVD (Stage 2)

The aim of this study was to evaluate the immunogenicity and safety of the Quinvaxem vaccine (a liquid combination vaccine against diphtheria, tetanus, B. pertussis, hepatitis B and H. influenzae Type B). Healthy Vietnamese infants received three doses of vaccine at 2, 3 and 4 months of age according to the local Expanded Programme on Immunisation (EPI) schedule

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 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

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.

This is a follow-up of Study A3L11 (NCT00404651). Immunogenicity To describe the antibody persistence following a primary series vaccination of either DTaP-IPV-Hep B-PRP~T or Infanrix hexa™. To describe the immunogenicity of a booster dose of DTaP-IPV-HepB-PRP~T in a subset of subjects. Safety - To describe the safety profile after a booster dose of DTacP-IPV-HepB-PRP~T.

Haemophilus influenzae is an important pathogen which can cause primary infection and respiratory viral infection in infants and leaded to secondary infections. The infection of haemophilus is a major cause of morbidity and mortality in infants and children. At present, the developed conjugant Hib vaccine is proved to be safe and effective. Because Hib vaccine can prevent meningitis, pneumonia, epiglottis inflammation and other serious infection caused by Hib bacteria, the WHO suggested that Hib vaccine should be included in the infant's normal immune programming. Since the use of meningitis aureus polysaccharide vaccine, incidence of a disease in recent years is declined and maintain to the level of 0.5 per 1/100 thousand. But meningitis aureus polysaccharide vaccine with a relatively poor immune response in the infants under the age of two, and the remaining 60% with a low antibody level and a short duration. According to the present immunization schedule, to reach the median level of antibody levels there are at least 4 doses in need. So it is meaningful to improving vaccine immunogenicity, to provide high levels of long-term protection and to reduce the number of injections. After the phase I study which was conducted in August, 2011, the safety profile of this vaccine is proved to be acceptable. The phase III study is aimed to further evaluate the safety and the immunization of the vaccine. The objective of this study is to evaluate the safety of the group A, C polysaccharide meningococcal and type b haemophilus influenzal conjugate vaccine.

This study will investigate safety and reactogenicity of a monovalent conjugated vaccine against Haemophilus influenzae type b in healthy children
