“We want our people to be protected,” Mr. Edwards said. “This is the way that we accomplish that. It is the way we can make sure that we return to normalcy and are able to safely gather.”
Dr. A. Mark Fendrick, the director of the University of Michigan Center for Value-Based Insurance Design, said in an interview that there was a compelling case for conducting lotteries but that they should be open only to people who were fully vaccinated.
“The people that we need to reach to get vaccinated, independent of their political affiliation, have been shown to be those populations who are likely to buy lottery tickets,” he said.
Dr. Fendrick, a primary-care physician who has studied consumer incentives for health care behavior for three decades, said it was too early to determine the effectiveness of the lotteries. In some states, he said, the lotteries coincided with making the vaccine available to teenagers, which could skew the numbers. He suggested comparing the vaccination rates in states with lotteries to those without them.
“I really want to see Michigan versus Ohio,” he said.
On Wednesday, North Carolina will hold its first lottery drawing as part of a similar vaccination push. Every other week, it will give away $1 million and a $125,000 scholarship to an adult and a teenager who get the vaccine.
In Oregon, however, the pace of vaccinations slipped since May, when Gov. Kate Brown announced a $1 million giveaway, The Oregonian reported this month.
Charles Boyle, a spokesman for Ms. Brown, said in an email on Tuesday night that the drop-off in vaccinations was to be expected as more residents had the shot. Oregon, he said, needed to inoculate less than 42,000 people to reach its target of at least 70 percent of adults having received at least one shot.
