In March Professor Marc Lipsitch — Director of Harvard's Center for Communicable Disease Dynamics — abruptly found himself a global celebrity, his social media following growing 40-fold and journalists knocking down his door, as everyone turned to him for information they could trust.
Here he lays out where the fight against COVID-19 stands today, why he's open to deliberately giving people COVID-19 to speed up vaccine development, and how we could do better next time.
As Marc tells us, island nations like Taiwan and New Zealand are successfully suppressing SARS-COV-2. But everyone else is struggling.

Even Singapore, with plenty of warning and one of the best test and trace systems in the world, lost control of the virus in mid-April after successfully holding back the tide for 2 months.
This doesn't bode well for how the US or Europe will cope as they ease their lockdowns. It also suggests it would have been exceedingly hard for China to stop the virus before it spread overseas.
But sadly, there's no easy way out.
The original estimates of COVID-19's infection fatality rate, of 0.5-1%, have turned out to be basically right. And the latest serology surveys indicate only 5-10% of people in countries like the US, UK and Spain have been infected so far, leaving us far short of herd immunity. To get there, even these worst affected countries would need to endure something like ten times the number of deaths they have so far.
Marc has one good piece of news: research suggests that most of those who get infected do indeed develop immunity, for a while at least.
To escape the COVID-19 trap sooner rather than later, Marc recommends we go hard on all the familiar options — vaccines, antivirals, and mass testing — but also open our minds to creative options we've so far left on the shelf.
Despite the importance of his work, even now the training and grant programs that produced the community of experts Marc is a part of, are shrinking. We look at a new article he's written about how to instead build and improve the field of epidemiology, so humanity can respond faster and smarter next time we face a disease that could kill millions and cost tens of trillions of dollars.
We also cover:
• How listeners might contribute as future contagious disease experts, or donors to current projects
• How we can learn from cross-country comparisons
• Modelling that has gone wrong in an instructive way
• What governments should stop doing
• How people can figure out who to trust, and who has been most on the mark this time
• Why Marc supports infecting people with COVID-19 to speed up the development of a vaccines
• How we can ensure there's population-level surveillance early during the next pandemic
• Whether people from other fields trying to help with COVID-19 has done more good than harm
• Whether it's experts in diseases, or experts in forecasting, who produce better disease forecasts
