COVID-19 Scenario Modeling Hub Round 8 Announcement

Scenario details for the latest round of the COVID-19 Scenario Modeling Hub (additional info below) are now posted on the corresponding GitHub (


This is an open call for teams to participate in the latest round of the COVID-19 Scenario Modeling Hub, a multi-model effort to provide 6-month ahead projections of cases, hospitalizations, and deaths in US states. The project started in December 2020 and has generated 7 rounds of projections thus far; further, the group has established tight connections with public health officials so that projections are used for planning purposes and decision-making. For example, Round 4 results were published in an MMWR (


Building upon earlier rounds, projections for this round focus on potential effects of waning immunity and resulting protection against infection and severe disease. As this is an ongoing effort, we include this update on the status of the hub in case you may be interested in participating in this or future rounds. To simplify participation, the submission format follows that of the COVID-19 Forecast Hub (with some metadata additions). Please note that submissions for this round are due on 17 August 2021 and that only data available through 14 August 2021 should be used to inform projections.
