Bone Marrow and Peripheral Blood Immune Responses Study

Longitudinal Analysis of Bone Marrow and Peripheral Blood Immune Responses to Influenza Vaccination in a Healthy Adult Cohort

About This Trial

The purpose of this study is to evaluate the immune response of the killed flu vaccine in healthy subjects. Participants in this study are considered to be healthy volunteers. Influenza ("Flu") infection carries a risk of serious illness. This is an open label and single arm observational study designed to assess the humoral response to influenza vaccination and the longevity of humoral immunity to influenza vaccination in healthy adults. Enrolled subjects will receive licensed seasonal inactivated influenza vaccine (administered as a part of the study). Participants will donate serial samples of blood and bone marrow aspirate for immunology monitoring. Repeated measurements of humoral immunity will be obtained at 7 days, 28 days, 90 days and at one year post vaccination to assess the magnitude, clonal diversity and persistence of B-cell responses to influenza vaccination.

Who May Be Eligible (Plain English)

Who May Qualify: - All genders, races and ethnic groups (inclusive of women and minorities) are eligible for this trial, as influenza and the associated range of clinical issues accompanying influenza infection can impact people of all genders, races and ethnic groups. It is anticipated that the distribution of study participants will be diverse with regard to these demographics. - Adults able to provide consent on their own - Healthy adults Who Should NOT Join This Trial: - Adults unable to consent - Women who are pregnant or nursing a child may not take part in this study. If a woman of childbearing potential is enrolled in this study, she and the study doctor must agree on a method of birth control to use throughout the study. Enrollees who think that they may have gotten pregnant during the study must tell the study doctor immediately. Pregnant women will be taken out of the study. - Prisoners - Cognitively impaired or individuals with impaired decision-making capacity - Individuals who are vulnerable to coercion or undue influence (human fetuses, or neonates of uncertain viability or non-viable neonates, minors/children, and cognitively impaired adults) will not be eligible for participation in this study. Always talk to your doctor about whether this trial is right for you.
