model_version: "1.0"
methods: For each state our scenario projections are generated using a mechanistic model with S[Sv]E[Ev]I[Iv]HR compartments, where 'v' subscripts indicate vaccinated. The model is calibrated to the 2023-24 data, and extrapolated through the 2024-25 season.

methods_long: "We use the population and vaccine time series provided by the Scenario Hub and
\ assume that the infection-susceptibility of vaccinated individuals accounts for one half \
\ of vaccine effectiveness against severe disease. The model is calibrated to 2023-24 season adult \
\ and pediatric COVID hospital admissions. Calibration assumes that last season fell \
\ somewhere between scenarios E and F. Additionally, calibration includes a preference for \
\ periodic/quasi-periodic trajectories. Calibration is a two-stage process. The first stage \
\ uses a traditional optimizer to find a centroid for the hyper-cube used in the second stage. \
\ The national projection profiles are calculated as \
\ the sum of states using pseudo-randomly ordered state level profiles. "\
