64 Clinical Trials for Various Conditions
The purpose of this research study is to evaluate the immune response to the H1N1 influenza or "flu" vaccine. The "immune response" is how your body recognizes and defends itself against bacteria, viruses, and substances that may be harmful to the body. HIV-1 infected children typically respond more poorly to vaccines compared to uninfected, healthy children and so this study hopes to learn whether or not the body will successfully produce enough antibodies (proteins that fight infection) that will prevent or fight the H1N1 flu virus. There is no information yet on the safety or immune response to this vaccine in children infected with HIV.
Background: - Researchers want to see if a new drug reduces flu disease in people treated with this drug versus a placebo. The drug has an antibody that may help the immune system fight the flu. Placebo is only sugar and water. All participants will get the flu virus. They may or may not develop flu symptoms. Objective: - To see if the drug CR6261 reduces flu disease in people treated with this drug versus a placebo. Eligibility: - Healthy nonsmokers ages 18 45. Design: * Participants will be screened under a separate protocol. * Participants must use contraception or abstinence for several weeks before and after the study. They must have no alcohol for 1 day before each visit. Any medicine must be approved by the study doctor until after follow-up. * Participants will stay in a hospital isolation unit for at least 10 days. * They will have: * Medical history * Physical exam * Blood and urine tests * Heart and lung test * Tests for drugs and alcohol * Throughout their stay, participants will: * Be closely watched by a medical team * Have nasal washes and swabs several times a day * Participants will have the flu virus sprayed in each nostril. * The next day, participants will get either study drug or placebo through a soft plastic tube placed in a vein by needle. It will take 2 hours. They will not know which they get. * Participants can go home after 10 days if they test negative for the flu 2 days in a row. * Participants will have daily questionnaires at home and 2 follow-up visits over 2 months.
This is a multicenter, escalating dose-ranging study to assess the safety, reactogenicity and immunogenicity of 3 different novel H1N1 influenza vaccine constructs delivered i.m. as a single dose vaccination on day 0.
The overall goal of this study is to study influenza vaccine responses in HIV infected individuals. Immunocompromised individuals require special protection from influenza, but may not respond appropriately to the standard killed vaccine. Patients who receive the H1N1 flu vaccine as part of their standard of care will be asked to donate blood samples for immunologic studies. These studies will determine whether participants were able to produce the appropriate antibodies to the vaccine and possibly identify predictors of vaccine responsiveness. Our hypothesis is that vaccine responsiveness to the new H1N1 influenza vaccine will be compromised in HIV infected patients.
This study is designed to characterize the safety and immunogenicity of a' pandemic influenza (H1N1) candidate vaccine GSK2340274A in adults 19 to 40 years who have never received influenza vaccination.
The purpose of this research study is to collect information on problems that patients with the novel H1N1 influenza and/or the seasonal influenza experience. Novel H1N1 flu is also called the swine flu. Seasonal influenza is also called the regular flu. The purpose of this study is to collect information from patients who are infected with either the novel H1N1 or the seasonal flu and to determine what makes patients critically ill with these infections. The goal is to develop a registry that will aid investigators in determining specific markers that lead to development of severe illness in these infections.
Children and people infected with HIV are particularly susceptible to influenza infections. This study testED the safety and effectiveness of a vaccine for the new H1N1 influenza virus in children and youth infected with HIV.
Both pregnant women and people infected with HIV are at increased risk of viral infection, including influenza infection. Pregnant women infected with HIV may be at particular risk of infection from the new H1N1 influenza virus. This study tested the safety and immunogenicity of an H1N1 influenza vaccine in pregnant women infected with HIV.
The purpose of this study is to assess the safety and the body's immune response (body's defense against disease) to an experimental H1N1 influenza vaccine in people with asthma. The study will enroll 350, and possibly up to 400 healthy adults ages 12 and older with mild, moderate, or severe asthma. Participants will be randomly assigned to 1 of 2 possible vaccine groups: group 1 will receive 15 mcg of H1N1 vaccine; group 2 will receive 30 mcg of H1N1 vaccine given as two 15 mcg injections. Both groups will receive vaccine injections on days 0 and 21. Study procedures include: medical history, physical exam, spirometry, maintaining a memory aid and, and blood sample collection. Participants will be involved in study related procedures for approximately 7 months.
The purpose of this study is to see how the body reacts to different strengths of the H1N1 flu shot when it is given with or without an "adjuvant." An adjuvant is a substance that may cause the body to produce more antibodies when it is given with a vaccine. This study will also compare how age affects the body's response to the H1N1 flu shot. In this study, 3 strengths of the H1N1 flu shot will be tested combined with an adjuvant. In addition, 2 strengths of the H1N1 flu shot will be tested without adjuvant. Two H1N1 flu shots of the same strength, with or without adjuvant, will be given about 3 weeks apart. Participants will include up to 800 healthy adults, approximately 500 individuals ages 18-64 and 250 individuals greater than or equal to age 65. Study procedures include: physical exam, blood samples, completing a memory aid to record vaccine side effects, medications and daily oral temperature. Participants will be involved in study related procedures for up to 13 months.

The Purpose Of This Study Is To Assess The Safety, Immunogenicity, And Tolerability Of A H1N1 Vaccine In Healthy Adults
A total of 51 children between the ages of 4 and 9 will be randomized to receive a two dose schedule of either licensed live attenuated A/California/07/09 influenza vaccine (LAIV) or licensed inactivated A/California/07/09 influenza vaccine (IIV) or IIV followed by LAIV separated by 28 days. Children with prior vaccination or natural infection with novel H1N1 influenza will be excluded. Randomization will be stratified by pre-existing HAI titers to the previous winter's seasonal H1N1 A/Brisbane/57/07 reference virus.
Unlike most influenza viruses, the 2009 H1N1 virus has affected people between 5 and 40 years old more often than people 60 years old or older. It may be that older people have had greater exposure to previous strains of H1N1 influenza, and this previous exposure protects them from infection. This study will examine how older people respond to a version of the H1N1 virus vaccine that includes a live, noninfectious version of the virus.

The purpose of this study is to evaluate the safety of a 2009 H1N1 influenza vaccine in pregnant women and to determine how their body reacts to different strengths of the vaccine. Two strengths of the H1N1 influenza vaccine will be tested. Since it is not known if the response to the vaccine in pregnant women is the same or different than in non-pregnant women, the study also includes a group of women who are not pregnant for comparison. Participants include 200 pregnant women and 100 non-pregnant women ages 18-39. Study procedures include physical exams, several blood samples and maintaining a memory aid to document daily temperature and side effects for 8 days following vaccination. Participants will be involved in study related procedures for about 6 months.
The purpose of this study is to evaluate an investigational 2009 H1N1 influenza vaccine to determine vaccine safety in pregnant women and the body's immune response (body's defense against disease) to different strengths of the H1N1 influenza vaccine. In this study, 2 strengths of the H1N1 influenza vaccine will be tested (given 3 weeks apart). Participants will include approximately 120 healthy pregnant women, ages 18-39 years, in their second or third trimester of pregnancy (14-34 weeks gestation). Study procedures will include 2 doses of vaccine, blood samples, cord blood samples at delivery, and recording temperature and vaccine side effects in a memory aid for 8 days following each vaccination. Participants will be involved in study related procedures for about 7 months.
