Intrinsic defects in B cell response to seasonal influenza vaccination in elderly humans

Open access

Abstract

We have evaluated the serum response to seasonal influenza vaccination in subjects of different ages and associated this with the specific B cell response to the vaccine in vitro. Although the serum response has previously been shown to decrease with age, this has largely been associated to decreased T cell functions. Our results show that in response to the vaccine, the specific response of B cells in vitro, as measured by AID (activation-induced cytidine deaminase), the in vivo serum HI (hemagglutination inhibition) response, and the in vivo generation of switch memory B cells are decreased with age, as evaluated in the same subjects. This is the first report to demonstrate that intrinsic B cell defects with age contribute to reduced antibody responses to the influenza vaccine. The level of AID in response to CpG before vaccination can also predict the robustness of the vaccine response. These results could contribute to developing more effective vaccines to protect the elderly as well as identifying those most at risk.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
