Filter by:purpose of this study is to assess the safety and immunogenicity of two MVA smallpox vaccine injections in healthy adults that are 18-35 years of age with a history of mild to moderate Atopic Dermatitis.
The currently available stock of smallpox vaccine would be insufficient in the face of an incident of smallpox attack. Thus, new manufacturing methods for smallpox vaccine is urgently needed because previous manufacturing methods using calf lymph are no longer acceptable in the view of current standards. Recently, CJ corporation in Republic of Korea has developed cell-culture derived smallpox vaccine (CJ-50300) which was manufactured by infecting MRC-5 cells. The aim of this phase 1 clinical trial were to assess safety, reactogenicity, and immunogenicity of CJ-50300.
This study will examine how people s immune systems respond to inoculation with vaccinia virus the standard vaccine used to protect against smallpox and how these responses correlate with symptoms they develop after receiving the vaccine. People 18 years of age and older who are scheduled to receive smallpox vaccination as a routine part of their employment (e.g., laboratory worker, health care worker, or emergency response worker) may be eligible for this study. They may or may not have been vaccinated previously. In addition, individuals who were vaccinated against smallpox at least 6 months before starting the study may participate as control subjects. All candidates will be screened with a brief medical history and physical examination. Participants in the following vaccination categories will undergo the procedures described for their group: Vaccine Recipient Frequent Follow-up Participants will come to the NIH Clinical Center every 2 to 3 days for a total of 7 visits over a 2-week period. At each visit, starting the day of vaccination, they will have the following procedures: - Brief skin examination, possibly with photographs of skin lesions; - Throat and skin swabs for vaccinia virus culture; - Blood draw (about 8 teaspoonfuls). Additional blood samples will be collected 1 month after vaccination and again within a year after vaccination. The blood will be analyzed for the immune response to the vaccine, genetic differences that might influence differences in immune response, and the presence of vaccinia virus. Participants will fill out a diary card every day for 3 weeks after vaccination to record any symptoms. Individuals who develop symptoms lasting more than 2 weeks, such as persistent or new skin lesions, will return to the clinic for additional skin exams and blood tests. Individuals who develop vaccine side effects may have a urine culture for vaccinia virus. Vaccine Recipient Infrequent Follow-up Participants will come to the NIH Clinical Center for blood tests on the day of vaccination, 4 weeks after vaccination, and once again within a year after vaccination. At each visit, 6 teaspoonfuls of blood will be drawn. This group will also include individuals who have been vaccinated within 8 months of entering the study and are not currently receiving the vaccine, but for whom blood samples are not available. Control Group Vaccinated at Least 6 Months Before Entering the Study Participants will come to the NIH Clinical Center for blood tests every 2 to 3 days for 2 weeks, then at 1 month after the first blood draw, and again within a year of the first blood draw. About 8 teaspoonfuls of blood will be drawn at each visit.
The purpose of this study is to compare the immunogenicity and safety of an investigational smallpox vaccine in subjects with atopic dermatitis to healthy volunteers.
The purpose of this study is to gather information on the safety and immunogenicity of an investigational smallpox vaccine in HIV infected populations. Subjects will receive two vaccinations
The primary objective of this study is to evaluate the immune response after a single vaccination of pre-immune subjects compared to two vaccinations in naive subjects. In addition the study further investigates the cardiac safety profile of MVA-BN® in a healthy population compared to placebo.
The purpose of this study is to assess the safety and immunogenicity of two MVA smallpox vaccine injections in healthy adults that are 18-35 years of age with HIV infection
Primary Objective: To estimate the smallpox vaccination take rate in healthy young adults not previously vaccinated with a smallpox vaccine. Secondary Objectives: To describe antibody response to vaccination and evaluate the take for each subject at various timepoints for each batch and pooled batches and to evaluate local signs, symptoms, and overall safety in healthy young adults not previously vaccinated with a smallpox vaccine.
The purpose of this study is to assess the take rate (formation of a typical postvaccinal lesion)and the safety and immunogenicity of the smallpox vaccine Elstree-BN.
The objective of the study is to find the optimal dose for the smallpox candidate vaccine IMVAMUNE (MVA-BN). For this purpose the study compares IMVAMUNE (MVA-BN) administered at three different dose levels.
