Abstract

Over 3 billion doses of inactivated vaccines for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been administered globally. However, our understanding of the immune cell functional transcription and T cell receptor (TCR)/B cell receptor (BCR) repertoire dynamics following inactivated SARS-CoV-2 vaccination remains poorly understood. Here, we performed single-cell RNA and TCR/BCR sequencing on peripheral blood mononuclear cells at four time points after immunization with the inactivated SARS-CoV-2 vaccine BBIBP-CorV. Our analysis revealed an enrichment of monocytes, central memory CD4+ T cells, type 2 helper T cells and memory B cells following vaccination. Single-cell TCR-seq and RNA-seq comminating analysis identified a clonal expansion of CD4+ T cells (but not CD8+ T cells) following a booster vaccination that corresponded to a decrease in the TCR diversity of central memory CD4+ T cells and type 2 helper T cells. Importantly, these TCR repertoire changes and CD4+ T cell differentiation were correlated with the biased VJ gene usage of BCR and the antibody-producing function of B cells post-vaccination. Finally, we compared the functional transcription and repertoire dynamics in immune cells elicited by vaccination and SARS-CoV-2 infection to explore the immune responses under different stimuli. Our data provide novel molecular and cellular evidence for the CD4+ T cell-dependent antibody response induced by inactivated vaccine BBIBP-CorV. This information is urgently needed to develop new prevention and control strategies for SARS-CoV-2 infection.

  • Crosstalk of specific T cells and B cells following COVID-19 vaccine treatment has been found.

    “In addition, it has been found that the crosstalk of specific T cells and B cells following COVID-19 vaccine treatment [220, 221].”

    From Single-cell sequencing to multi-omics: technologies and applications (2024) · cites this paper as [221]

    The Discussion (page unavailable) reports CD4+ T-cell expansion after BBIBP-CorV vaccination and suggests a Th2–B-cell immune response. It also hypothesizes that CD4+ T cells help memory B cells produce antibodies after a booster. This supports a possible T–B-cell interaction, but the paper does not report crosstalk as an established finding. (LLM, conf=0.84)

  • Single-cell technologies shed light on host-pathogen dynamics, immune responses, and advanced therapeutic strategies, especially in COVID-19.

    “In the realm of infectious diseases, the technologies shed light on host-pathogen dynamics, immune responses, and advanced therapeutic strategies, especially in COVID-19 [145, 146, 219–223].”

    From Single-cell sequencing to multi-omics: technologies and applications (2024) · cites this paper as [221]

    The Introduction (page unavailable) describes single-cell methods as tools for studying immune responses during COVID-19, and the Discussion (page unavailable) reports vaccine-elicited T-cell responses. This supports the immune-response part of the claim, but the paper studies healthy vaccine recipients rather than host–pathogen dynamics and does not establish that these methods illuminate advanced therapeutic strategies.

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.
