Krispy Kreme Doughnuts is offering a free glazed doughnut per day for the rest of the year to anyone who shows their COVID-19 Vaccination Record Card.

Food writer Corby Kummer spoke to Boston Public Radio on Thursday about the company’s announcement.

“How many people do you think are actually going to take advantage of it every day?” he said. “Not nearly as many as the much of free publicity Krispy Kreme has gotten for this announcement.”

The company also sweetened the deal for its employees, Kummer noted.

“I’m going to praise Krispy Kreme because they’re also offering up to four hours of paid time off for each vaccination for their employees,” he said.” “This is really important to incentivize employees.”

Kummer is a senior editor at The Atlantic, an award-winning food writer, and a senior lecturer at the Tufts Friedman School of Nutrition and Policy.
