Vaccines Clinical Trials

Purpose of the study. The purpose of the project is to evaluate the feasibility, acceptability, and cost effectiveness of providing influenza vaccine in schools to children in grades Kindergarten through 6th grade. Hypothesis 1: School based influenza vaccination (SIV) will increase the overall rate of influenza vaccination in school children. Hypothesis 2: Higher intensity parent notification about school based influenza vaccination does not increase immunization rates compared to low intensity. Hypothesis 3: School based vaccination from the perspective of mass vaccinators is cost neutral. Read Less

This study will evaluate the effectiveness of chemotherapy and a combination of vaccines to treat metastatic breast cancer (breast cancer that has spread beyond the breast) in patients whose cancer cells have a protein called carcinoembryonic antigen (CEA) on their surface. Patients who require surgery or radiation therapy, or both, will receive these treatments as well. Patients 18 years of age and older with previously untreated metastatic breast cancer may be eligible for this study. Newly diagnosed patients may not have received prior chemotherapy. Patients previously diagnosed with local disease may have received chemotherapy or radiation therapy at least 18 months before entering the current study. Patients may have received hormonal therapy for stage IV disease. Candidates are screened with a medical history and physical examination, blood and urine tests, x-rays, heart and lung tests, and a test to determine the presence of CEA on their tumor cells. Participants undergo the following procedures: 1. Central venous line: Under local or general anesthesia, an intravenous catheter (plastic tube) is inserted into a major vein in the chest. It is used to give chemotherapy and other medications and to withdraw blood samples. 2. Apheresis: Before beginning treatment and at various times before and after chemotherapy, patients undergo apheresis to collect white blood cells for later re-infusion at the time of immunizations and to evaluate the body's response to the vaccines. For this procedure, blood is collected through the central venous catheter and circulated through a machine that separates the white cells from the rest of the blood. The white cells are removed and frozen for later use. The rest of the blood is returned to the patient through the catheter. 3. First vaccine: Before starting chemotherapy, patients receive one subcutaneous (under the skin) injection of a vaccine called rV-CEA-Tricom, along with subcutaneous injections of granulocyte macrophage colony stimulating factor (GM-CSF) (Sargramostim), a drug that stimulates the bone marrow to release white blood cells and white cell precursors into the bloodstream. 4. Chemotherapy: * Taxol (paclitaxel)/Cytoxan (cyclophosphamide): Patients receive three to five cycles of Taxol and Cytoxan. Taxol is given as a continuous 72-hour intravenous (intravenous (IV), through a vein) infusion and Cytoxan is given daily for 3 days, intravenously, over 1 hour. Cycles are 21 to 42 (usually 28) days. After each cycle, patients also receive growth colony stimulating factor (G-CSF) (a drug that helps boost white cells. Read Less

The purpose of this study is to learn whether or not giving a tetanus/diphtheria vaccination ("tetanus shot") before giving pneumococcal vaccine makes the pneumococcal vaccine more effective without causing too many side effects. Read Less

A Phase 1, Randomized, Placebo-Controlled, Observer-Blinded, Escalating Dose-Ranging Study to Assess the Safety, and immunogenicity of 6 different recombinant RSV-F formulations in healthy adults (18 to 49 years of age). Study Objectives: Primary: * To assess and compare the safety, reactogenicity, and tolerability of 6 RSV-F protein particle vaccine formulations. Secondary: * To assess and compare the immunogenicity (neutralizing antibody and total anti-F antibody) of the 6 RSV-F protein particle vaccine formulations * To confirm the "dose sparing" and "value added" effects of the aluminum phosphate adjuvant Read Less

This study is designed to evaluate in a controlled manner the effect of Prevnar® on the immune responses of Pentacel™ Primary Objective - Stage I: To compare the immune responses elicited by an infant series of Pentacel™ when given at different times from or concurrently with a Pneumococcal conjugate vaccine (Prevnar®). Primary Objective - Stage II: To compare the immune responses elicited by a 4th dose of Pentacel™ when given at different times from or concurrently with Prevnar®. Read Less

This multi-center study will be conducted in the United States with up to 80 healthy adult subjects. Subjects will be scheduled to receive a total of two (2) injections with 1 injection each administered. Subjects will be randomized according to a randomization scheme. Read Less

This Phase 2 study is a double blind, placebo-controlled, randomized, multicenter investigation of rBV A/B-40 vaccine or placebo in healthy adults, using two different three-dose dosing schedules. Read Less

This Phase 2(a) clinical trial is designed as a dose-blinded, block-randomized, multi-center study to select a dosage and schedule of rF1V vaccine for further studies based on the immune response up to Day 210. Additional immunogenicity and safety/reactogenicity data will be collected through Day 540. Selection of dosage and schedule will be based on GMCs and seroconversion rates for anti-F1, anti-V and anti-rF1V antibody titers. Approximately 400 healthy adult volunteers will be enrolled (100 per group) in this study. Read Less

Primary Objective: To evaluate for each influenza strain the non-inferiority of Investigational Fluzone vaccine to the standard Fluzone® vaccine in healthy subjects aged 6 to 35 months or 3 to 8 years. Secondary Objectives: * To describe the immunogenicity of of Investigational Fluzone vaccine to the standard Fluzone® vaccine in healthy subjects aged 6 to 35 months or 3 to 8 years. * To describe the safety of of Investigational Fluzone vaccine to the standard Fluzone® vaccine in healthy subjects aged 6 to 35 months or 3 to 8 years.

The purpose of this study is to evaluate the safety of administering a combination vaccine (DTaP-HepB-IPV; Pediarix™) to infants at birth, 2 and 6 months compared to the administration of a HepB vaccine at birth and the same combination vaccine at 2, 4, and 6 months of age. Additionally, researchers will assess the body's antibody response (proteins produced by the body's immune system that help fight infections) following each vaccine dose. The study will enroll 5 healthy newborns, ages 0-5 days. Participants will be involved in study related procedures for up to 288 days, including blood sample collection and 5 study visits. Read Less
