Filter by:The purpose of this study is to assess the safety and immune response (body's defense against disease) to an experimental H1N1 influenza vaccine in healthy adult and elderly populations. The study will enroll up to 450 healthy adults ages 18 and older with no history of H1N1 infection or vaccination. Two hundred individuals will be 18-64 years old, and the other 200 will be greater than or equal to 65 years of age. Participants will be randomly assigned to 1 of 2 possible vaccine groups: group 1 will receive 15 micrograms (mcg) of H1N1 vaccine; group 2 will receive 30 mcg of H1N1 vaccine. Both groups will receive vaccine injections on days 0 and 21 in the arm muscle. Study procedures include: medical history, physical exam, maintaining a memory aid, and blood sample collection. Participants will be involved in study related procedures for approximately 7 months.
The purpose of this study is to evaluate the antibody response to one and two doses of influenza A/H1N1v vaccine in healthy adults.
The purpose of this study is to assess the safety and immune response (body's defense against disease) to an experimental H1N1 influenza vaccine against the 2009 H1N1 virus. This study will help determine how and when the H1N1 flu shot should be given with the seasonal flu shot to make it most effective. The 650 participants will be divided into the following age groups: infants from 6 months-36 months old, children 36 months-9 years old, and adolescents 10-17 years old. Each age group will have 200 children. There are 4 treatment groups in each age level. Study procedures include: medical history, targeted physical exam based on history, maintaining a memory aid, and blood sample collection. Participants will be involved in the study for about 8 months.
This is an open label phase I study, to assess the safety of a novel influenza vaccine, MVA-NP+M1. All volunteers recruited will be healthy. Twelve volunteers will be administered with a single dose of 5 x 10^7 pfu of MVA-NP+M1 via the Intradermal (ID) route (group 1). Sixteen volunteers will receive Intramuscular (IM) MVA-NP+M1. The first 8 volunteers will be administered a single dose of 5 x 10^7 pfu of MVA-NP+M1 followed by a further eight receiving 2.5 x 10^8 pfu of MVA-NP+M1 (group 2). The 3rd group will be split into 3 groups of 10 volunteers in the age ranges 50-59, 60-69 and 70 and above and administered intramuscularly with a single dose of 1.5 x 10^8 pfu of MVA-NP+M1. Safety data will be collected. The secondary aim of this study will be to assess the cellular immune responses generated by each dose.
The objective of the study is to evaluate immunogenicity between different formulations of GSK Biologicals' investigational vaccine GSK2186877A.
This study is designed to determine the optimal dose of JVRS-100 and assess safety, tolerability and immunogenicity of Fluzone® vaccine administered with JVRS-100 adjuvant at one of three dose levels compared to Fluzone® vaccine administered alone, in 472 adults aged ≥65 years.
The purpose of the study is to determine whether the combination treatment of Chinese medicinal herbs and oseltamivir is more effective than single oseltamivir in treating novel influenza A (H1N1) pneumonia.
The purpose of this study is to determine whether Chinese medicinal herbs are effective and safe for treating novel influenza A (H1N1) infection.
The study described here will immunize children with trivalent influenza vaccine (TIV) and determine whether this reduces influenza illness among the immunized children and their older family members. The comparison or control group for the children receiving influenza vaccine will be children immunized with inactivated poliovirus vaccine (IPV). The study will also provide information on the amount of disease produced by influenza in the study population.
The study will assess the safety, reactogenicity, and tolerability of VAX102 when given with Trivalent Inactivated Influenza Vaccine (TIV) delivered in the same arm as two separate IM injections in healthy adults 18 to 49 years. The investigators will measure the immunogenicity of the VAX102 when given with TIV and the antibody response to TIV when given with VAX102 compared to TIV alone.
