CoRiCal: COVID-19 Risk Calculator

CoRiCal is a tool to help people make decisions about getting a COVID-19 vaccine. It shows how the vaccine can lower the chance of catching, getting sick from or dying from COVID-19. It also shows the chance of getting rare side effects from the vaccines.

The tool shows the chance based on your age, sex, and vaccinations. You can choose to see the results ‘as a chance' or 'per million people' by clicking on the tabs.

The results shown are only a guide. The tool shows the average result for people with the same sex and age as you. This tool does not consider other things that can change your chance of infection or illness from COVID-19. This includes your general health, where you work or go to school, or your COVID-19 safe behaviours.

When making decisions about getting a COVID-19 vaccine, you should also consider how your chance might change in the future. This might include a change in the number of cases in your community or travel to an area with more cases.

Watch these videos for examples of how to understand the risk calculator results: general model, kids model, long covid model.
