The Million-Dollar Misfire of Vaccine Lotteries

In May 2021, as the U.S. vaccination campaign started to lose momentum, several U.S. states and some cities arrived at the same conclusion: To boost uptake, they’d launch vaccine lotteries, giving locals who’d gotten their shot the chance to win a million or more dollars. But a new study published in JAMA Health Forum on Friday suggests that, on their own, the lotteries launched for vaccinated residents in 19 states failed to achieve their goals of encouraging people to take the Covid vaccine. It found no significant difference in rates of vaccine uptake in states that launched lotteries compared to those that did not. “Everyone was rooting for this to work, but you’ve got to check,” says Andrew I. Friedson, an associate professor of economics at the University of Colorado Denver and an author of the report. “The way the evidence has stacked up it seems that there are better ways to spend our money.”
