It describes how each variant spread through the population, incorporating cross-immunity between variants. The model is calibrated using seroprevalence data, PCR positivity rates, and variant sequencing, providing insights into how prior infections shaped susceptibility to future waves.2025-04-12T00:00:00Z2026-06-03T18:50:21.429Z2025-07-15T10:03:08.945ZMODEL250412000110.1038/s41467-024-47556-2
