Among the Vaccine Hesitant

There are a host of articles today about the US reaching a vaccination tipping point at which the key challenge is no longer the supply of vaccine but the supply of people willing to take it. Like “herd immunity” it isn’t a binary, clear-cut moment. It’s incremental. We’re approaching it now and the challenge will accelerate over the next two to four weeks. In many ways this challenge is a product of our success. In January I don’t think anyone thought we’d have widespread availability and half of all adults vaccinated in April. But we did it.
