Data-driven seroclustering of longitudinal dried blood spot samples from 808 Swedish young adults captures immune responses to both SARS-CoV-2 infection and vaccination exposures.
- Why it matters: Population protein studies often miss transient, time-dependent immune shifts; repeated self-sampling can reveal dynamic immune trajectories linked to real-world exposures.
- What they did: The study profiled ~2400 DBS samples (2020–2022) for SARS-CoV-2 serology, anti-interferon autoantibodies, and 365 inflammation proteins, then linked results to infection/vaccination, traits, genetics, and blood counts.
- The result: Stable IFNAR1 and IFNGR2 autoantibodies associate with the duration of self-reported COVID-19 symptoms, and paired pre/post samples show temporal protein changes after infection (LAP3) and vaccination (TIMP3).
