Abstract

SARS-CoV-2 spike mRNA vaccines 1–3 mediate protection from severe disease as early as ten days after prime vaccination 3 , when neutralizing antibodies are hardly detectable 4–6 . Vaccine-induced CD8 + T cells may therefore be the main mediators of protection at this early stage 7,8 . The details of their induction, comparison to natural infection, and association with other arms of vaccine-induced immunity remain, however, incompletely understood. Here we show on a single-epitope level that a stable and fully functional CD8 + T cell response is vigorously mobilized one week after prime vaccination with bnt162b2, when circulating CD4 + T cells and neutralizing antibodies are still weakly detectable. Boost vaccination induced a robust expansion that generated highly differentiated effector CD8 + T cells; however, neither the functional capacity nor the memory precursor T cell pool was affected. Compared with natural infection, vaccine-induced early memory T cells exhibited similar functional capacities but a different subset distribution. Our results indicate that CD8 + T cells are important effector cells, are expanded in the early protection window after prime vaccination, precede maturation of other effector arms of vaccine-induced immunity and are stably maintained after boost vaccination.

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

  • The majority of COVID-19 vaccines evoke humoral and cellular immune responses against the SARS-CoV-2 spike protein; these responses may not prevent infection but robustly protect against severe COVID-19 for certain periods of time.

    “The majority of COVID-19 vaccines are designed to evoke humoral and cellular immune responses against the SARS-CoV-2 spike protein — responses that may not prevent infection but robustly protect against severe COVID-19, at least for certain periods of time11,150–157.”

  • mRNA vaccination generates spike-specific memory CD4+ and CD8+ T cell responses.

    “mRNA vaccination has also been shown to generate spike-specific memory CD4+ and CD8+ T cell responses (19–22).”
  • SARS-CoV-2 mRNA vaccination efficiently primed antigen-specific CD4+ T cells and CD8+ T cells.

    “Consistent with recent studies, SARS-CoV-2 mRNA vaccination efficiently primed antigen-specific CD4+ T cells and CD8+ T cells (Fig. 5, C and D) (20–22).”

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.
