Filter by:Many plasma donation centers have Tetanus immunization programs that are implemented in order to collect plasma with high levels of tetanus antibodies. The immunization program requires participants to receive multiple tetanus vaccinations over a period of time with the goal of hyper-immunizing them to tetanus. Their antibody-rich plasma is then used to manufacture a tetanus immunoglobulin product which helps with the prophylaxis and treatment of tetanus disease. The Tetanus vaccine previously used for these programs is no longer being manufactured. Therefore, we must evaluate the safety and efficacy of a different vaccine when used for this purpose. The only other FDA approved Tetanus vaccines currently available for adults in the US are combination vaccines that also immunize against Diphtheria and/or Pertussis. In this study, the investigators will evaluate two vaccines that are combinations of Tetanus and Diphtheria (Td). Investigators will not evaluate any vaccines containing Pertussis antigen. The vaccines to be evaluated are manufactured by MassBiologics and Sanofi Pasteur (Tenivac). The package insert for these vaccines indicates they should be administered to previously vaccinated people once every 10 years. However, this study will evaluate whether they are safe and effective for dosing every 90 days. The investigators hypothesize that at least 25% of study subjects will have a positive response to at least one of the five planned doses. Each vaccine will be evaluated separately.
This was a dose and formulation ranging study to assess the safety and immunogenicity of SP0173 in healthy adolescents, adults, and older adults in the United States (US). Primary Objective - To describe the safety profile of each SP0173 investigational formulation. Observational Objective: - To describe the immunogenicity of each SP0173 investigational formulation.
This study is being conducted to assess impact of maternal immunisation against pertussis in infants ≤12 months of age before and after introduction of pertussis maternal immunisation in Bogota, Colombia from January 2005-December 2014.
The purpose of this study is to evaluate if the intestinal microbiota influences rotavirus vaccine immune responses in healthy adult volunteers.
The objective of this study is to assess the immunogenicity and safety of the DTaP-IPV combination vaccine compared with those of separate DTaP and IPV vaccines administered to healthy infants at 2, 4, and 6 months of age.
The purpose of this study is to assess duration of protection for GSK DTaP vaccines in preventing pertussis.
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 evaluate the immunogenicity and safety of GSK Biologicals' Infanrix hexa, given in the primary vaccination schedule to infants born to pregnant women who participated in study 116945 [DTPA (BOOSTRIX)-047]. This study will help us evaluate if the presence of transplacentally transferred maternal antibodies interfere with the immune response to primary vaccination with Infanrix hexa and a co-administered pneumococcal conjugate vaccine given as a part of this study in infants.
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)
Evaluate the persistency of immune response against Haemophilus influenzae type b by assessing anti-PRP antibody levels in children vaccinated with either Hib-CRM197 or Hib-TT booster vaccine approximately 4 years before.
