Episode notes

There's no such thing as 'herd immunity' says Dr Andrew Wakefield. The idea that once you've had a virus, or been vaccinated against it, you have a long term sterilizing immunity and you're unlikely to get it again is wishful thinking. Once r goes very high, and that number, herd immunity goes over 100%. So it's a moot point anyway. We're all going to get it.

When it comes to the COVID-19 vaccination, is the risk of myocarditis greater than the benefit to a healthy male teen? Is natural immunity really better than vaccination--and were we right to mask the kids? Dr. Vinay Prasad of the University of California San Francisco talks with EconTalk host Russ Roberts about what we learned and didn't learn from COVID so far and how we should handle a pandemic going forward.
