Virus Diseases Clinical Trial
Official title:
Evaluating the Durability of the Human Immune Response to the JYNNEOS Modified Vaccinia Ankara-Bavarian Nordic (MVA-BN) Vaccine
This study is designed to evaluate the magnitude and duration of the human adaptive immune response to the JYNNEOS Modified Vaccinia Ankara-Bavarian Nordic (MVA-BN) vaccine in the blood, lung mucosa, skin and bone marrow.
Orthopoxvirus vaccination leads to very high magnitude antigen-specific T cell responses and neutralizing antibody responses that can be detected in blood decades after vaccination. Despite a large number of previous studies of human immune responses to Modified Vaccinia Ankara (MVA) vaccination in blood, very few of these previous studies evaluate the human mucosal immune response to MVA in the lung and skin, or the immune response to MVA vaccination in the bone marrow. The development of methods to explore human immune responses in these key immunologic compartments now allows the evaluation of the induction of immune responses in these human tissues using the MVA vaccine system. ;
