A Krispy Kreme doughnut a day for the vaccinated

Fans of Krispy Kreme's classic glazed doughnuts will soon have a sweet incentive to get vaccinated.

Starting Monday, Americans who have received a COVID-19 shot can claim a free doughnut every day -- for the rest of the year.

Kelly Miller rushed to the store as soon as she heard the news.

"If that's what it takes to get more people vaccinated, like, if people are going to, I already was, but if people are going to get vaccinated to get a free doughnut, do it."

Customer Steve Hines says getting vaccinated is rewarding enough.

"I mean, that is the reward -- staying alive, but the doughnut is just like a little pat on the back, just reinforces that."

But not everyone thinks the giveaway is a good idea, with some linking the risks of obesity and the severity of illness with COVID-19.

Krispy Kreme's Chief Marketing Officer Dave Skena says their doughnuts are best enjoyed in moderation.

"You know, we're encouraging everyone to have an occasional treat and recognize that they just did something that's going to help all of us get to a post-COVID life."

Krispy Kreme says it's making its free treats available every day until 2022, so no one gets left out, even if it's not their turn to get vaccinated just yet.
