What do I wish I had known in early 2020? Other than to buy shares in toilet paper, Zoom and vaccine companies, I wish I had known that a safe and effective vaccine against severe disease and death from Covid-19 would arrive within a year – and that reinfection would nevertheless become a major issue in managing the disease.

At the very beginning of the pandemic, several governments – including in Sweden, Netherlands and the UK – believed the best path through this crisis was to allow a controlled spread of infections through the population, especially the young and healthy, in order to reach some static state against the virus. The idea was that “the herd” who got infected would protect a more vulnerable minority.
