Filter by:Randomized controlled trial of 2 strategies to provide adults with the Tdap vaccine to patients presenting to the emergency department. Rates of vaccination as well as effects on department efficiency will be measured.
This is a single-center, randomized, active-controlled, parallel-group, open-label, phase I study to evaluate safety and immunogenicity of single injection of LBVD or Eupenta co-administered with Imovax Polio in healthy adults.
This is an observational study designed to describe the immune profile of toddlers and preschoolers with acellular priming after receiving a booster dose of pertussis vaccine.
Background: When a person is exposed to something that causes an infection, the body sends a type of cell called CD8 T cells to attack it. Those cells are also found in breast milk. Nursing mothers pass these cells to their child, which helps the child fight infections, too. Researchers want to learn more about how CD8 cells work to keep people healthy. Objective: To learn more about how the human body fights off infections. Eligibility: People age 18 years and older who either have an infection, are suspected to have an infection, or recently got a vaccine. The household contacts of these people and people who have not been recently exposed to any infection are also needed. Design: Participants will be screened with a medical and health history and physical exam. They may have blood tests. The first study visit can be the same day as screening. It can be up to 3 months later. For those visits, screening tests will be repeated. At the first visit, participants will have blood collected from an arm vein. Participants who are breastfeeding may provide a small sample of breast milk. They may collect it at home or bring a pumping device to NIH to collect it. NIH can also provide a breast pump. Participants may be contacted for up to 1 year after the first visit to give samples of blood and/or breast milk. Up to 4 additional visits, which will each take about 1 hour, may be scheduled. A personal physician or local lab can collect blood from participants and ship it to NIH. Breast milk cannot be shipped.
This is a phase II, randomized double-center, and observer-blind controlled pilot vaccine trial in 11 to 15 years old healthy subjects to assess the immunogenicity of the genetically detoxified pertussis toxin (rPT) included in a novel acellular pertussis vaccine (Pertagen®) manufactured by BioNet-Asia when delivered by the intramuscular route to adolescents previously primed and boosted with chemically-detoxified PT, along with Td-pur® and in comparison with that of Boostrix® dTpa. At Day 0, eligible volunteers will undergo a venous bleed for the determination of baseline values and enter the randomization scheme, being allocated to one of two groups: A (Pertagen® + Td-pur®), B (Boostrix® dTpa). Randomized participants will receive one dose of Pertagen® and Td-pur® (Group A) or 1 dose of Boostrix® dTpa (Group B) by intramuscular injection in the deltoid. All subjects will be observed in the Plateforme de Recherché Pédiatrique for 30 minutes after immunization. Post-immunization local and systemic reactions will be followed up for 7 days after immunization. Adverse events will be followed for 28 days after immunization. At Day 28, a second visit (study end visit) will take place for safety evaluation and blood draw for immunogenicity evaluation. Blood draws performed on Day 0 (Baseline) and Day 28 will be used to evaluate immune response to study vaccines. The primary statistical analysis will be performed with visit 2 (Day 28) data to compare the immunogenicity and safety of one dose of Pertagen®, given simultaneously with Td-pur®, to those elicited by Boostrix® dTpa.
The purpose of this study is to evaluate the immune response, safety and reactogenicity after receiving combined DTPa-IPV/Hib vaccine when administered as a three-dose primary vaccination course at 3, 4.5 and 6 months of age and as a booster dose at 18 months of age in Russian healthy children according to the Russian immunisation schedule
Phase III, open, mono-center study in 177 infants who received a dose of Hep B vaccine at birth or within 1 month after birth. Infants will receive Sanofi Pasteur's DTaP-IPV-Hep B-PRP-T combined vaccine (study vaccine) at 2, 3, and 4 months of age. All subjects will provide blood samples for immunogenicity assessment at baseline (pre-vaccination) and at 30 days following the third vaccination. Regarding safety, solicited reactions and unsolicited non-serious adverse events (AEs) will be collected up to 7 days and up to 30 days after each vaccination, respectively. Serious adverse events (SAEs) will be collected throughout the study trial (from Visit 1 to Visit 4)
This study aims to assess and confirm the adequate immunogenicity and safety profile of the Sanofi Pasteur's DTaP-Hep B-IPV-PRP-T fully liquid combined hexavalent vaccine administered in HIV-exposed uninfected infants and in HIV-exposed infected infants. The primary objectives of the study are: - To evaluate the immunogenicity of the study vaccine 1 month after the 3-dose primary series in HIV-exposed infected and in HIV-exposed uninfected infants. - To describe the persistence of all antibodies before receipt of the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants. - To evaluate the immunogenicity of the study vaccine 1 month after the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants. The secondary objectives of the study are: - To describe the safety profile after each and all doses of the study vaccine administered as a 3-dose infant primary series in HIV-exposed infected and in HIV-exposed uninfected infants. - To describe the safety profile of the study vaccine administered as a booster in HIV-exposed infected and in HIV-exposed uninfected infants.
This is a multicenter extension study of two European randomized, double-blind studies (V419-007 and V419-008). It describes long-term persistence of hepatitis B and pertussis antibody responses in healthy 4- to 5 year old children previously vaccinated with Vaxelis® or INFANRIX® hexa
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.
