Abstract

It is not fully understood why COVID-19 is typically milder in children 1–3 . Here, to examine the differences between children and adults in their response to SARS-CoV-2 infection, we analysed paediatric and adult patients with COVID-19 as well as healthy control individuals (total n = 93) using single-cell multi-omic profiling of matched nasal, tracheal, bronchial and blood samples. In the airways of healthy paediatric individuals, we observed cells that were already in an interferon-activated state, which after SARS-CoV-2 infection was further induced especially in airway immune cells. We postulate that higher paediatric innate interferon responses restrict viral replication and disease progression. The systemic response in children was characterized by increases in naive lymphocytes and a depletion of natural killer cells, whereas, in adults, cytotoxic T cells and interferon-stimulated subpopulations were significantly increased. We provide evidence that dendritic cells initiate interferon signalling in early infection, and identify epithelial cell states associated with COVID-19 and age. Our matching nasal and blood data show a strong interferon response in the airways with the induction of systemic interferon-stimulated populations, which were substantially reduced in paediatric patients. Together, we provide several mechanisms that explain the milder clinical syndrome observed in children.

  • Younger patients may be more capable of mounting the interferon-driven, anti-viral innate response critical to GTAU and developing robust adaptive immunity compared to adults and the elderly.

    “Younger patients may be more capable of mounting the interferondriven, anti-viral innate response critical to GTAU and developing robust adaptive immunity compared to adults and the elderly (Kumar et al., 2018; Yoshida et al., 2022).”

    From Gene Therapy-Associated Uveitis (GTAU): Understanding and mitigating the adverse immune response in retinal gene therapy (2025) · cites this paper as Yoshida et al., 2022

    The Results (‘Distinct changes in children and adults’) report stronger local interferon responses in children that may provide better protection against SARS-CoV-2. The Results (‘Diverse immune repertoire in children’) suggest that greater T-cell receptor diversity could enable a faster, more efficient adaptive response. Our copy does not mention GTAU or establish that these responses are critical to it. (LLM, conf=0.85)

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.
