Functionally impaired antibody response to BNT162b2 booster vaccination in CVID IgG responders.
Article in The Journal of allergy and clinical immunology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAlthough previous studies described the production of IgG antibodies in a subgroup of patients with common variable immunodeficiency (CVID) following messenger RNA vaccinations with BNT162b2 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (CVID responders), the functionality of these antibodies in terms of avidity as measured by the dissociation rate constant (k
objectiveWe sought to analyze in CVID responders and healthy individuals, the avidity of anti-SARS-CoV-2 serum antibodies and their neutralization capacity as measured by surrogate virus-neutralizing antibodies in addition to IgG-, IgM-, and IgA-antibody levels and the response of circulating (peripheral blood) follicular T-helper cells after a third vaccination with BNT162b2 SARS-CoV-2 messenger RNA vaccine.
methodsBinding IgG, IgA, and IgM serum levels were analyzed by ELISA in patients with CVID responding to the primary vaccination (CVID responders, n = 10) and healthy controls (n = 41). The binding avidity of anti-spike antibodies was investigated using biolayer interferometry in combination with biotin-labeled receptor-binding-domain of SARS-CoV-2 spike protein and streptavidin-labeled sensors. Antigen-specific recall T-cell responses were assessed by measuring activation-induced markers by flow cytometry.
resultsAfter the third vaccination with BNT162b2, IgG-, IgM-, and IgA-antibody levels, surrogate virus-neutralizing antibody levels, and antibody avidity were lower in CVID responders than in healthy controls. In contrast, anti-SARS-CoV-2 spike protein avidity was comparable in CVID responders and healthy individuals following primary vaccination. Follicular T-helper cell response to booster vaccination in CVID responders was significantly reduced when compared with that in healthy individuals.
conclusionsImpaired affinity maturation during booster response provides new insight into CVID pathophysiology.
