There has been quite a lot of excitement recently concerning the trials of COVID-19 vaccines. It remains to be seen when they will become widely available, whether they are as effective – as safe – as claimed. In the meantime, it is good to remind ourselves how the trials and their analysis are carried out.

My new article at The Conversation gives an overview of some numbers behind the vaccine trials and plans for the deployment. If you know Spanish, there is even a translation available!
