Comparison of Immune Response to Booster Vaccines in Blood Transplant Patients and Healthy Volunteers Clinical Trials Resources presented on Clinical Trials Search is not meant to be a substitute for proven health advice, calls or treatment with a real medical. We aren't mDs. Always consult your doctor on Comparison of Immune Response to Booster Vaccines in Blood Transplant Patients and Healthy Volunteers conditions. Clinical Trials Search.org is a website dedicated to listing clinical research studies in human subjects. Comparison of Immune Response to Booster Vaccines in Blood Transplant Patients and Healthy Volunteers Clinical research trials and Comparison of Immune Response to Booster Vaccines in Blood Transplant Patients and Healthy Volunteers healthcare trials take place in a lot of of localities throughout the U.S.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically assess the effectiveness of new does drugs. The function of the studies / projects is to figure out specific human medical questions. Clinical trials are a popular means for doctors, government agencies, and private sector corporations to find cures for all varieties of conditions, like Comparison of Immune Response to Booster Vaccines in Blood Transplant Patients and Healthy Volunteers. Comparison of Immune Response to Booster Vaccines in Blood Transplant Patients and Healthy Volunteers Clinical Trials and other clinical trials allow volunteers to access health treatment options before they are available to the masses. Many times the subjects receive professional assistance for free, and every now and again they are compensated for their time. Sometimes there is a cost for a Comparison of Immune Response to Booster Vaccines in Blood Transplant Patients and Healthy Volunteers clinical trial. Human subjects often obtain the finest healthcare possible for their Comparison of Immune Response to Booster Vaccines in Blood Transplant Patients and Healthy Volunteers condition. Hazards are a reality, nevertheless, and might include additional or frequent dr. calls, health hazards (potentially life-jeopardizing), and/or the treatment being uneffective. Trials are federally regulated with stern guidelines to protect clinical trials patients.

Comparison of Immune Response to Booster Vaccines in Blood Transplant Patients and Healthy Volunteers
For Condition: Healthy,Stem Cell Transplantation,Active Immunity
Status: Completed
Sponsor(s): National Institute of Allergy and Infectious Diseases (NIAID) ,
Synopsis: This study will compare the immune system response to booster vaccines for tetanus/diphtheria and hepatitis B in healthy volunteers with that of patients who have had a blood transplant. (A blood transplant is an infusion of donated stem cells-i.e., cells that mature into white blood cells, red blood cells and platelets). The study will also look at how age of the blood cell donor and recipient, the type of blood transplant, the amount of certain types of white cells in donor blood, and other variables may influence the vaccine response among the transplant patients. This study includes normal volunteers and patients who have had a blood transplant. Healthy volunteers between the ages of 18 and 60 who have previously been vaccinated with the hepatitis B or tetanus/diphtheria vaccine and have not had hepatitis B may be eligible for this study. Patients enrolled in a blood cell transplant study at NIH who are between 5 and 60 years old, have been vaccinated against tetanus/diphtheria, and have not had hepatitis B may be eligible. Candidates will be screened with a medical history and blood tests. Those enrolled in the study will have about 2 tablespoons of blood drawn before vaccination with a standard tetanus/diphtheria booster shot. Volunteers who have previously been vaccinated with the hepatitis B vaccine and all blood transplant patients will also receive a hepatitis B vaccination. Participants will have blood drawn (from 1 to 5 tablespoons) up to once a week after vaccination for no more than 8 weeks to evaluate the immune response to vaccination.
Details: This study will compare booster vaccine responses in patients undergoing hematopoietic stem cell transplant (HSCT) to a group of healthy volunteers. Responses among different types of HSCT will be compared to each other as well. Serum antibody titers to vaccine antigens and quantification of antigen specific lymphocytes will be followed. Approximately 15 healthy subjects and 40 patients will be enrolled.
