BY-COVID Use-case

Good information leads to tasty outcomes

If you want to make a great birthday cake you need fresh ingredients and a good recipe to combine them. Without one or the other the cake is doomed.

Public health decisions in pandemics are much the same: you need good information and a way to bring the information together. For example, if you don’t know how effective vaccines are or how severe the next variant is, it becomes impossible to formulate good policies. Data are the key ingredient for evidence-based policies, but they are useless without the framework of a good recipe. To be useful, scientific data needs to be correctly collected, stored and linked with other data in a controlled but accessible environment.

If policymakers are the cooks of public health policies to manage pandemics, the BY-COVID project is providing the best possible recipes to combine data to inform their decisions. The goal is to support policymakers and provide the tools required to make decisions that are rooted in reality and proportional to the risks that are faced.


Would you eat in a restaurant using expired ingredients, wild recipes that are never tested and no hygiene standards? In the same way, public health policies need good data, well-tested methods to combine the data and standards to ensure data protection. With the right raw materials, equipment and resources, everything is in place to make the best food possible.
