Background: * No treatment is known to improve survival for prostate cancer patients who have not been helped by previous treatments with hormones and chemotherapy. * An experimental vaccine called prostate specific antigen (PSA)/TRICOM contains genes for a protein produced by prostate cancer cells called prostate-specific antigen (PSA). The vaccine can trigger the immune system to make cells that may be able to recognize and attack the cancer cells that make PSA. * Granulocyte macrophage colony stimulating factor (GM-CSF) is an approved drug that is usually given to increase a patient's white blood cell count or to stimulate the immune system. * 1Samarium-153-ethylene diamine tetramethylene phosphonate (53Sm-EDTMP) is a radioactive drug that has been approved for many years to treat advanced prostate cancer. It is given through a vein and can be targeted directly to tumors in the bone where it can relieve pain caused by bone lesions. Radiation also increases the level of certain proteins inside the tumor, making it easier for the immune system to find and kill the tumor cells. * When laboratory mice were given just vaccine, just radiation, or a combination of both, the combination was most effective in treating tumors. Objectives: -To determine if combined treatment with PSA/TRICOM vaccine and 153Sm-EDTMP radiation can delay progression of prostate cancer better than radiation alone. Eligibility: -Patients who have advanced prostate cancer that has worsened despite treatments with hormones, have two or more bone lesions related to their prostate cancer, and have had prior treatment with docetaxel chemotherapy. Design: * Patients are randomly assigned to receive radiation alone (Arm A) or radiation with vaccine and sargramostim (Arm B). * Arm A receives 153Sm-EDTMP radiation starting on study day 8 and repeated every 12 weeks. * Arm B receives a priming vaccine on study day 1 and radiation on day 8. Radiation therapy is repeated every 12 weeks. Boosting vaccines are given on days 15 and 29 and then monthly. GM-CSF is given with each vaccination (on the day of the vaccination and for the next 3 days) to enhance the immune response. Vaccinations and GM-CSF are given as injections under the skin, usually in the thigh. Radiation therapy is given through a vein. * Patients are monitored regularly with physical examinations, blood and urine tests, and scans to evaluate safety and treatment response. * Patients who are human leukocyte antigen serotype within HLA-A A serotype group (HLA-A2)-positive undergo apheresis, a procedure similar to donating blood, for obtaining immune cells called lymphocytes to measure the immune response to the vaccine.

Background: Drugs given to treat cancer (chemotherapy) can weaken the human immune system. But it can also become weaker because of aging. Interleukin (IL)-7, a molecule produced naturally in the body, can help improve the function of the immune system. Researchers want to study the effects of IL-7 on immune system function in two different groups of older people. One group will be people who have received vaccines before IL-7. The other group will be people who have received Vaccines after IL-7. Objectives: To evaluate the effect of IL-7 on the immune system responses to vaccines in older people following chemotherapy. Eligibility: People at least 60 years of age who have recently finished chemotherapy for breast, colon, or bladder cancer. Design: * People in the study will be screened with a physical examination, medical history, and blood tests. Other screening tests, such as tumor imaging, may also need to be performed. * Everyone will receive a series of five different vaccines commonly used to prevent diseases. We will compare the responses of people in Sequence 1 who will receive vaccines before IL-7 with the responses of people in Sequence 2 who received the same vaccines after IL-7. * The vaccines will be given randomly in two Arms at different times. * Arm 1: diphtheria and tetanus, polio, pneumonia (with two booster shots), hepatitis B (with two booster shots), and hepatitis A (with one booster shot), * Arm 2: hepatitis A (with one booster shot), hepatitis B (with two booster shots), pneumococcal (with two booster shots), diphtheria and tetanus, polio, pneumonia (with two booster shots) * There are 5 vaccines to be given to each subject, following one of two randomly assigned sequences of vaccine administration (Sequence 1 or Sequence 2). * The first vaccine arm contains the two diphtheria protein containing vaccines tetanus and diphtheria (Td) and pneumococcal conjugate 13 (PCV13) and polio. The second vaccine arm contains the Hepatitis A and Hepatitis B vaccines. Subjects will either get tetanus, diphtheria, polio, and pneumonia vaccines before IL-7 therapy (Sequence 1) or hepatitis A and hepatitis B vaccines before IL-7 therapy (Sequence 2). The response to vaccines will be evaluated 4 weeks after vaccination. This will be followed by IL-7 therapy, then administration of the other group of vaccines. Therefore, subjects on both arms will receive the same set of vaccines, just at different times with respect to IL-7 therapy. Read Less

The purpose of this study is to generate additional data on the immunogenicity and safety of revaccination with Fluzone Intradermal (ID) or Fluzone Intramuscular (IM) vaccine. Primary Objective: * To evaluate and describe the safety profile of revaccination with Fluzone ID for all participants. Secondary Objective: * To describe immunogenicity following revaccination with Fluzone ID or Fluzone IM. Read Less

Compared to young adults, the elderly mount a lower antibody response to vaccination. Thus, improvement of the immune response to influenza vaccination in this age group, which is at higher risk for influenza-related morbidity and mortality, represents an important unmet need. Primary Objectives: Immunogenicity: * To demonstrate lot consistency of the Fluzone High Dose (Fluzone HD) manufacturing process through evaluation of the immune responses elicited by three different lots. * To demonstrate the superiority of Fluzone HD vaccine compared to standard-dose Fluzone® vaccine. Secondary Objectives: Immunogenicity: * To describe the seroprotection of Fluzone HD compared to that of standard dose Fluzone® vaccine. Safety: * To describe the safety profile of Fluzone HD, in terms of solicited -, unsolicited adverse and serious adverse events post-vaccination. * To describe clinical information on some additional defined criteria during the six months following vaccination.

The aim of the study is to generate data on key parameters associated with assessment of influenza vaccines in individuals 50-64 years of age Primary Objective: * To describe the immunogenicity of High-Dose Trivalent Inactivated Influenza Vaccine (TIV) compared to TIV. * To describe the safety profile of High-Dose Trivalent Inactivated Influenza Vaccine, as assessed by solicited adverse reactions collected for 7 days post-vaccination, and unsolicited adverse events (including Serious Adverse Events and Adverse Events of Special Interests) collected between Visit 1 and Visit 2 Read Less
