QCovid is an algorithm developed by the University of Oxford to predict the risk of someone catching, being admitted to hospital, or dying from COVID-19 in England, UK.

Based on data from 'the first few months of the pandemic', the model takes into account various socio-economic indicators, underlying health conditions such as diabetes and heart disease, body-mass index, and postcode (within Britain), among other factors, to return an 'absolute risk of a covid-19 associated death' or hospitalisation.

Following the launch of the tool an additional 1.7 million people were instructed to shield, with around 800,000 people moved up the priority list to be vaccinated. These include women with previous gestational diabetes but who were now healthy and could not understand why it was being recommended that they shield.

Some General Practitioners also described seeing healthy young men on the list. Young, healthy people who are less likely to have measurements such as body weight recorded in their health records, Irene Petersen, professor of epidemiology and health informatics at University College London, told The Guardian.

An updated version of the system was released in November 2021.
