# List of COVID-19 simulation models

COVID-19 simulation models are mathematical infectious disease models for the spread of COVID-19. The list should not be confused with COVID-19 apps used mainly for digital contact tracing.
Note that some of the applications listed are website-only models or simulators, and some of those rely on (or use) real-time data from other sources.

## Models with the most scientific backing

The sub-list contains simulators that are based on theoretical models. Due to the high number of pre-print research created and driving by the COVID-19 pandemic, especially newer models should only be considered with further scientific rigor.

### Vaccination monitors, models or dashboards

Note: The following (additional) resources are mostly based on actual data, not simulation. They might include predictive features, e. g. vaccination rate estimation, but in general are not based on theoretical or modeling grounds as the main list of this article. Nonetheless, forecasting remains important. (See for example the COVID-19 Forecast Hub)
* COVID-19 Dashboard - Center for Systems Science and Engineering (CSSE) at Johns Hopkins University (JHU)
* COVIDVaxView by the CDC
* Datahub Novel Coronavirus 2019 dataset - COVID-19 dataset Coronavirus disease 2019 (COVID-19) time series listing confirmed cases, reported deaths and reported recoveries.
* Impfdashboard.de - Germany's vaccination monitor
* Simulation der COVID19-Impfkampagne - Monitor for vaccination-campaign in Germany by Zi Data Science Lab
* The Institute for Health Metrics and Evaluation (IHME) COVID-19 Projections
