Vaccine Innovation: A Marvel of Modern Science and Modern Markets

We’ve already talked about different methods for distributing the vaccine in the face of limited supply on this blog (see my post and Doug Norton’s post). But today I want to talk about something different: the speed at which this vaccine was developed. It is truly amazing.

This chart from Nature (adapted from the fantastic Our World in Data) dramatically shows just how quickly the COVID-19 vaccine was developed compared with past vaccines. What used to take decades or even a century was done in mere months (yes, even with all the regulatory barriers today).

Exactly how we developed this vaccine so quickly is a complex story that involves the advanced state of modern science, incentives offered by concerned governments, and the harnessing of the profit motive to advance the public good. We don’t know all the details yet, and likely won’t for a long time since, like a pencil, no one person knows how to make and distribute a vaccine.
