Plans for COVID-19 Support in ICE

Once a vaccine has been approved for use by the FDA (either Expanded Access, EUA, or full licensure), the Advisory Committee on Immunization Practices (ACIP) holds an emergency meeting and publishes recommendations in a very quick time frame (i.e., days). HLN releases a version of ICE that includes updated COVID-19 forecasting as early as possible. The initial release contains COVID-19 logic that is known at the time of the release. As additional, relevant information on COVID-19 becomes available from official sources, HLN will continue to release additional versions of ICE, at appropriate times.
