Abstract

In order to develop predictive markers for a beneficial humoral immune response, we evaluated the in vivo and in vitro response to the pandemic (p)H1N1 vaccine in young and elderly individuals. We measured serum antibody response and associated this with the in vitro B-cell response to the vaccine, measured by activation-induced cytidine deaminase (AID). Both responses decrease with age and are significantly correlated. The percentage of switched memory B cells in blood, both before and after vaccination, is decreased with age. The percentage of switched memory B cells at t0 correlates with the hemagglutination inhibition response and therefore, we suggest that this may be used as a predictive marker for B-cell responsiveness. AID induced by CpG before vaccination also predicts the robustness of the vaccine response. Plasmablasts showed a trend to increase after vaccination in young individuals only. This report establishes molecular biomarkers of response, percentage of switched memory B cells and AID response to CpG, useful for identifying individuals at risk of poor response and also for measuring improvements in vaccines and monitoring optimal humoral responses.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Switched memory B cells are predictors of optimal antibody responses.

    “Using these markers, it has been shown that the percentage of switched memory B cells, the predictors of optimal antibody responses [114], decreases with age [115, 116].”
  • Serum antibody response to seasonal and pandemic influenza vaccines, and in vitro B-cell response after vaccination, both decrease with increasing age and are significantly correlated.

    “For example, the serum antibody response to both seasonal and pandemic influenza vaccines, as well as the in vitro B-cell response after vaccination, are both decreased with increasing age and are significantly correlated [114, 124, 125].”

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.
