Filter by:Immunization with the inactivated influenza vaccine with blood samples collected at 7 visits (baseline, day 7, 14, 28, 60, 90 and 180, fine needle aspiration (FNAs) from axillary lymph nodes at baseline, days, 4, 14, 28, 60 and 180. BMA at baseline, days 28 and 180.
The study will prospectively determine the clinical utility of non-pathogen specific cellular immunity assessment using the Quantiferon-Monitor to quantify the degree of immunosuppression. The investigators will use the results of the assay to predict whether patients develop opportunistic infections and predict organ rejection.
BCG vaccination has been found to provide greater protection against TB in the UK than in Malawi. This study compares immune responses in BCG-vaccinated and unvaccinated teenagers and young adults in Malawi and in the UK.
