The aim of the study is to evaluate a prototype quadrivalent influenza vaccine (QIV), the licensed 2010-2011 trivalent influenza vaccine (TIV) containing the primary B strain (B1), and the investigational TIV containing the alternate B (B2) strain in children. Primary Objective: To demonstrate non-inferiority of antibody responses to QIV compared with licensed 2010-2011 TIV (containing the primary B strain) and investigational TIV (containing the alternate B strain) as assessed by geometric mean titer (GMT) ratios for each of the four virus strains separately among children aged 6 months to less than 9 years of age Secondary Objective: To demonstrate superiority of antibody responses to each B strain in QIV compared with antibody titers following vaccination with the TIV that does not contain the corresponding B strain, as assessed by GMT ratios and seroconversion rates. Observational Objective: To describe the safety profile of QIV among subjects 6 months to less than 9 years of age, as assessed by solicited injection site and systemic adverse events (AEs) collected for 7 days post-vaccination, unsolicited adverse events collected from 21 days post-vaccination, and adverse events of special interest and serious adverse events (SAEs) collected from Visit 1 to Visit 2.

Randomized, double blind, multi-site, study in healthy adults, comparing safety and immunogenicity of two dosage levels of Norwalk VLP Vaccine with adjuvant/excipients and with placebo controls Primary Objective: * Safety as determined by occurrence of local intranasal symptoms or other symptoms as reported by a self-administered memory aid for 7 days after each vaccination and hematology, blood chemistry and physical examinations performed by the clinical research staff * Subjects will also be monitored for Serious Adverse Events (SAEs), and onset of any new medical conditions for 180 days following the last study vaccinations (Day 201). Secondary Objectives Evaluations of immunogenicity as determined by: * Geometric mean titers and seroconversion rate of serum anti- Norwalk VLP IgG and IgA * Stimulation of anti-Norwalk VLP IgA antibody secreting cells (ASC) * Presence of antigen specific memory B-cell response Cells will be collected and stored for possible future evaluation of Norwalk VLP-specific cell-mediated immune (CMI) responses Study Hypothesis: The incidence of adverse events after intranasal Norwalk VLP Vaccine will be the same as the incidence of adverse events after intranasal adjuvant/excipients alone. Norwalk VLP Vaccine and adjuvant/excipients will have a higher incidence of mild to moderate nasal adverse events compared to placebo but similar incidence of other adverse events. Two doses of the 100 µg of Norwalk VLP Vaccine will be more immunogenic than two doses of 50 µg of Norwalk VLP Vaccine. The post-vaccination serum antibody responses, the number of antibody secreting cells (ASC) and IgG and IgA memory B-cell responses directed against Norwalk Virus antigen will be increased after Norwalk VLP Vaccine compared to adjuvant/excipients and to placebo.

RATIONALE: Vaccines made from prostate cancer cells may make the body build an immune response to kill tumor cells. Colony-stimulating factors such as sargramostim may increase the number of immune cells found in bone marrow or peripheral blood. Interleukin-2 may stimulate a person's white blood cells to kill prostate cancer cells. Androgens can stimulate the growth of prostate cancer cells. Hormone therapy using nilutamide may fight prostate cancer by reducing the production of androgens. It is not yet known which treatment regimen is more effective for treating prostate cancer. PURPOSE: Randomized phase II trial to compare the effectiveness of vaccine therapy plus sargramostim and interleukin-2 with that of nilutamide alone in treating patients who have prostate cancer that has not responded to hormone therapy.

Pneumococcal disease is a serious bacterial infection that can affect different parts of the body, including the lungs. People with chronic illnesses, such as chronic obstructive pulmonary disease (COPD), have a greater risk of developing pneumonia and meningitis as a result of pneumococcal disease. This study will compare the immune response to two types of pneumococcal vaccines in adults with COPD. Read Less

The purpose of this study is to evaluate the production of antibodies to a new conjugate vaccine, NmVac4-A/C/Y/W-135-DT, as a measure of vaccine effectiveness, compared to the production of antibodies to a similar, licensed meningococcal (Groups A, C, Y, W-135) polysaccharide diphtheria toxoid (DT) conjugate vaccine. The investigators will also evaluate the safety of NmVac4-A/C/Y/W-135-DT™ conjugate vaccine compared to the licensed vaccine. The hypothesis is that the test vaccine is comparable to the licensed active control vaccine. Read Less

This study is to evaluate the safety, tolerability and immune response when 13-valent pneumococcal conjugate vaccine (13vPnC) and the trivalent inactivated flu vaccine (TIV) are given together to healthy adults aged 50-59 years who are naive to 23-valent pneumococcal polysaccharide vaccine (23vPS), or when the vaccines are given 1 month apart. It will also evaluate the immune response to 13vPnC once per year for 4 years and then to a second dose of 13vPnC given 5 years after the first dose. Read Less

The aim of this study is to determine the efficacy of Fluzone High-Dose compared to standard dose Fluzone for laboratory-confirmed or culture-confirmed influenza caused by influenza types/subtypes that are similar (for laboratory-confirmed) or antigenically similar (for culture-confirmed) to those contained in the respective annual vaccine formulations. Primary Objective: * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to laboratory-confirmed influenza caused by any influenza viral types/subtypes, associated with the occurrence of a protocol-defined influenza-like-illnesses (ILI). Secondary Objectives: * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to laboratory-confirmed influenza, caused by any influenza viral types/subtypes, associated with the occurrence of a protocol-defined ILI. * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to culture-confirmed influenza, caused by any influenza viral types/subtypes, associated with the occurrence of a protocol-defined ILI. * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to culture-confirmed influenza caused by viral types/subtypes antigenically similar to those contained in the respective annual vaccine formulations, associated with the occurrence of a modified Centers for Disease Control and Prevention (CDC)-defined ILI. * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to culture-confirmed influenza caused by any influenza viral types/subtypes, associated with the occurrence of a modified CDC-defined ILI. * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to culture-confirmed influenza caused by viral types/subtypes antigenically similar to those contained in the respective annual vaccine formulations, associated with the occurrence of a respiratory illness. * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to culture-confirmed influenza caused by any influenza viral types/subtypes, associated with the occurrence of a respiratory illness.

H7N9 viruses have caused a recent outbreak of severe illness in humans in China. The purpose of this study is to evaluate the safety and immune response of an H7N9 A/Anhui/13 ca influenza virus vaccine followed by an inactivated subvirion H7N9 vaccine at varying intervals. Read Less

The purpose of this study is to see if cyclosporine, taken when a patient begins highly active antiretroviral therapy (HAART), increases the number of CD4 T-cells (blood cells that fight infection) in a patient's blood. This study also will explore the safety of briefly giving cyclosporine to patients starting HAART. Read Less

The purpose of this study is to compare a new higher-dose influenza virus vaccine to the standard dose vaccine in elderly adults who can walk. Current influenza vaccines protect elderly against viral influenza but not as well as desired. It is expected that the higher doses vaccine can be given with little reaction, but this needs to be tested. Up to 410 people ages 65 years and older will be recruited from the community and from existing volunteer populations. Participants will receive either the high or standard dose injected in the muscle, remain in the clinic for 20 minutes afterward, and maintain a daily memory aid for 7 days. The memory aid will be reviewed by telephone 8-12 days after the injection and return to the clinic or contacted by telephone 6 months after the injection. Read Less
