Filter by:The purpose of this study is to determine the preferred dose of H1N1 pandemic influenza vaccine in a pediatric population, aged 6 months to 17 years, based upon assessments of immunogenicity and safety.
The objective of this study is to evaluate the immunogenicity and safety of GSK Biologicals' investigational vaccine GSK2340272A.
The primary safety objective of this study is to assess the safety of split- virion inactivated H1N1 vaccine with and without adjuvant when administered at the 7.5,15 or 30 mcg dose. The primary immunogenicity objective is to assess the antibody response following each dose of split- virion inactivated A(H1N1) vaccine with and without adjuvant. Participants will include up to 2200 healthy persons age 3 and older who have no history of novel influenza H1N1 2009 infection or novel influenza H1N1 2009 vaccination. This is a randomized, double-blinded, Phase II study in healthy males and non-pregnant females, aged 3 years and older. Subjects will be stratified by elders (equal to or more than 61 years), adults (18-60 years), adolescents (12-17 years) and children (3-11 years), elders and adolescents will be randomized into 5 dose groups (adjuvanted H1N1 vaccine of 7.5,15 or 30 mcg per dose or non-adjuvanted H1N1 vaccine of 15 or 30 mcg per dose), children will be randomized into 4 dose groups (adjuvanted H1N1 vaccine of 7.5 or 15 mcg per dose or non-adjuvanted H1N1 vaccine of 15 or 30 mcg per dose), adults will be randomized into 6 dose groups (adjuvanted H1N1 vaccine of 7.5,15 or 30 mcg per dose or non-adjuvanted H1N1 vaccine of 15 or 30 mcg per dose or placebo), 110 subjects per dose and age stratum will be to receive intramuscular influenza H1N1 vaccine. The H1N1 vaccine will be administered at Day 0 and Day 21. Following immunization, safety will be measured by assessment of adverse events through 21 days following the last vaccination (Day 42 for those receiving both doses), serious adverse events and new-onset chronic medical conditions through 6 months post the final vaccination (Day 180 after second vaccination), and reactogenicity to the vaccine for 8 days (Day 0-7) following each vaccination. Immunogenicity testing will be hemagglutination inhibiting (HAI) on serum obtained on the day 21 of each vaccination (prior to vaccination), on Day 21 after first vaccination, and 21 days following the second vaccination (Day 42).
Background: - Vaccines are substances used to try to create resistance (or immunity) to a disease and to prevent an infection. Researchers are testing a new DNA vaccine designed for a new type of influenza, often referred to as swine flu. The DNA vaccine will instruct the body to make a particular kind of influenza protein that the immune system will be able to recognize. - Researchers are interested in determining if the vaccine is safe and effective in humans, and would like to study the immune system's response to the vaccine. The vaccine will not give participants influenza; however, it may not be effective in preventing them from getting influenza at a later date. Objectives: - To evaluate the safety and tolerability of the VRC-FLUDNA057-00-VP influenza vaccine as administered to healthy adults. - To evaluate antibody responses to the new influenza vaccine. Eligibility: - Healthy adults between the ages of 18 and 70. Design: - Participants will have seven planned clinic visits during this study (enrollment day and study weeks 1, 4, 8, 9, 12, and 32). - All participants will receive three injections of the test vaccine, given as individual doses on day 0, day 28, and day 56 of the study. The vaccine will be given in the upper arm muscle. - Injections will be given using a needleless system that delivers the vaccine through the skin by using the pressure of carbon dioxide to inject the vaccine through the skin and into the muscle. Participants will remain at the National Institutes of Health (NIH) Clinical Center for at least 30 minutes after the injection to be monitored for any reaction. - Participants will be asked to keep a 7-day diary card after each injection to record their physical reactions to the vaccine. - Participants will be asked to return to the NIH Clinical Center as requested by researchers for additional blood tests and other procedures, as required by the study.
The objective of this study is to evaluate the immunogenicity and safety of GSK Biologicals' investigational vaccine GSK2340272A in children aged between 3 and 17 years.
This present study, randomized, single-blind, dose-ranging, multicenter study, will evaluate immunogenicity, safety and tolerability of two doses of an adjuvanted and not-adjuvanted new swine-origin influenza A/H1N1 virus monovalent subunit vaccine in healthy adult and elderly subjects. A booster dose will be administered 12 months after the first vaccination.
