Rotavirus infection is a common pediatric illness and is the leading cause of severe acute gastroenteritis (vomiting and diarrhea) in infants and young children. Since February of 2006, an oral vaccine to prevent rotavirus has been approved by the Food and Drug Administration (FDA). The company that makes the oral vaccine is Merck and Company. Since the FDA approval, the American Academy of Pediatrics (AAP) and that Advisory Committee on Immunization Practices (ACIP) has recommended the use of this oral vaccine in infants. A previous rotavirus oral vaccine, Rotashield, was removed from the market for concerns that it was causing an increase in a gastrointestinal (GI) disease called intussusception. However, the new rotavirus vaccine was studied by the manufacturer and was not found to cause an increase in the cases of intussusception. Intussusception is a disease in which a portion of the GI tract folds back on itself leading to GI tract obstruction or back-up. The manufacturer of the vaccine noted on package insert information that the vaccine was not studied, originally, in infants with a history of GI disorders or in infants who have had surgery on their abdomen. Currently, there is no information available in the scientific literature about the use of the oral rotavirus vaccine in infants with GI diseases or those who have had GI surgeries. The objective of the study is the assessment of safety and tolerability of the oral RotaTeq® vaccine for all infants participating in the study. All infants will be followed for clinical adverse events with active safety surveillance for the first 42 days after each dose and also monthly afterward for a total of 12 months from the first vaccination date. The secondary objective of the study is to quantify the immunologic response will occur in all of the infants in the study. Assessment of percentage of the number of infants who have a good immune response (three-fold rise in IgA titer or greater) to the complete rotavirus vaccine series (three oral vaccines in total) by a blood test to check the rotavirus immunoglobulin A (IgA) level in infants with short bowel syndrome compared to normal infants will occur. Infants, meeting eligibility criteria and whose parents have signed informed consent will have their study information collected. These infants will be tested for the presence of pre-vaccine anti-rotavirus antibody, IgA levels, as mentioned above. After the blood is obtained, participants will receive their first oral rotavirus vaccine dose between the ages of 6 weeks to 12 weeks of life per package insert information. This oral rotavirus vaccine may be administered with other routine pediatric vaccines at the participant primary care provider's office. The date of the rotavirus vaccine and lot number would be recorded on vaccine administration date cards. Most participants will have their vaccines given through the Infectious Disease clinic staff at the Children's Hospital of Michigan. Subsequent doses of the oral rotavirus vaccine will be given at a minimal interval between vaccines of four weeks. The third, and final vaccine dose must be given by 32 weeks of life. Any adverse reactions to the vaccine will be reported on the National Vaccine Adverse Event Reporting System and MedWatch forms. Finally, two weeks after the participants have had all three oral rotavirus vaccine doses, the second and final blood draw will take place for measuring the post-vaccine level of anti-rotavirus antibody, IgA. Participants in the study will be monitored by telephone contacts on days 7, 14, and 42 after each dose and within 48 to 72 hours of each dose of the rotavirus vaccine regarding any serious adverse events. Each infant will also be assessed in the clinical setting each week after a vaccine dose has been given. As above, parents of participants will be asked to fill out the vaccine report card and record the child's temperature, and any episodes of vomiting, diarrhea, blood in the stools or fussiness for the first seven days. The parents will also be asked to record any other events from day 8 through 42 after each vaccine is administered such as fever, ear infection, runny nose, etc. Afterward, parents will also have monthly phone call safety follow-ups during the 12 month period following the first vaccination. A Data Safety and Monitoring Board will oversee the study and it's progress and will have the ability to vote to stop the study. Read Less

This study will determine the safety and effectiveness of an experimental vaccine in controlling the abnormal growth of cells in patients with myelodysplastic syndrome (MDS, also known as myelodysplasia), acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), and chronic myeloid leukemia (CML). It will test whether the vaccine can increase the number of immune cells responding to the cancer and thereby slow progression of the illness, improve blood counts, reduce the need for transfusions of blood and platelets, or even achieve a disease remission. The vaccine contains part of a protein that is produced in large amounts by cells of patients with these cancers and an added substance called Montanide that helps the immune system respond to the vaccine. Sargramostim, another substances that boosts the immune response, is also given. Patients 18 to 85 years of age with MDS, AML, ALL or CML may be eligible for this study. Candidates are screened with a medical history, physical examination, blood tests, chest x-ray and bone marrow biopsy. Women of childbearing age also have a pregnancy test. Participants undergo the following: * Chemotherapy entering the study. * Leukapheresis to collect large amounts of white blood cells for infusion before vaccine administration. * Participants may need placement of a central line (plastic tube, or catheter) in the upper part of the chest to be used for giving chemotherapy, blood or platelet transfusions, antibiotics and white blood cells, and for collecting blood samples. * Weekly vaccine injections for nine weeks, given in the upper arm, upper leg or abdomen. * Sargramostim injections following each vaccination. * Standard of care treatment for MDS, AML, ALL or CML, which may include blood or platelet transfusions, growth factors, and drugs to control underlying disease and potential side effects of the vaccine. * Weekly safety monitoring, including vital signs check, brief health assessment, blood tests and observation after the vaccination, on the day of each vaccination. * Follow-up evaluations with blood tests and chest x-ray 3 weeks after the last vaccine dose and with blood tests and bone marrow biopsy 7 weeks after the last vaccine dose.

This study will evaluate the safety and effectiveness of a new vaccine, ALVAC-pp65, in boosting immunity to cytomegalovirus (CMV) infection in stem cell transplant donors. CMV is a member of the herpesvirus group, which includes herpes simplex virus types 1 and 2, varicella-zoster virus (which causes chickenpox), and Epstein-Barr virus (which causes infectious mononucleosis). Most adults are infected with CMV, but a healthy immune system keeps the virus in check, so that it does not cause harm. In people with a weakened immune system, such as transplant recipients, the virus can become reactivated. Medications for treating the infection may cause low blood counts and kidney damage, and, in some cases, the virus may cause death. The ALVAC-pp65 vaccine is intended to improve immunity against CMV in stem cell donors and thereby prevent its reactivation in recipients. It is made from a virus that ordinarily infects canaries. The virus is weakened so that it cannot infect the person who receives it, and it is modified to carry a copy of a CMV gene called pp65. This gene instructs cells to make CMV proteins that the vaccine recipient's immune system can produce antibodies to, thus conferring immunity to the disease. Persons 18 years of age or older who are scheduled to donate stem cells for a patient in an NIH protocol and who are not allergic to eggs, egg products, or other vaccines, may be eligible for this study. Candidates are screened with a medical history, physical examination, and blood tests. Participants receive three vaccinations one week apart beginning at least 3 weeks before the scheduled stem cell donation. They are observed for 30 minutes after each vaccination to look for any immediate side effects of the vaccine. Approximately 3 tablespoons of blood are drawn before each vaccination and 1 week after the last vaccination to evaluate vaccine safety. Blood samples are also collected at the screening evaluation, 3 weeks after the start of vaccination, and 3 months after the last vaccination to check for CMV immunity. Participants keep a diary, recording any reactions to the vaccine and any change in medications. They are contacted by telephone for follow-up 3 months after the last vaccination to report any additional symptoms. Read Less

This phase I trial studies the side effects and best dose of autologous T-antigen-presenting cells (T-APC) vaccine following therapeutic autologous lymphocytes (CTL) and cyclophosphamide in treating patients with metastatic melanoma. Aldesleukin may stimulate lymphocytes, such as CTL, to kill melanoma cells. Treating lymphocytes with aldesleukin in the laboratory may help the lymphocytes kill more tumor cells when they are put back in the body. Vaccines made from melanoma antigen may help the body build an effective immune response to kill tumor cells and may boost the effect of the CTL. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving T-APC vaccine after CTL and cyclophosphamide may be an effective treatment for melanoma Read Less
