In an effort to motivate Philadelphia residents to get a COVID-19 vaccine, the city launched a vaccination raffle that awarded residents random prizes from $1,000 to $50,000 for the shot.
However, University of Pennsylvania researchers A paper was published in the Social Science Research Network Earlier this week that showed the incentive lottery was not a success.
They analyzed how to call the lottery File Fax Lottery, affected the city’s vaccination rates compared to neighboring counties that did not provide incentives. They found no evidence of any meaningful increase in vaccinations in Philadelphia County.
“Overall, the results from our experience suggest that the regret lottery may not be reliable An effective tool for policymakers hoping to encourage vaccination at this point in a population-wide release of a vaccine,” Read research paper.
The Philly Vax Sweepstakes competition was launched on June 7 and there were sketches on June 21, July 6 and July 19. The city conducted the drawings in partnership with Penn’s Wharton School of Business.
The Philly Vax lottery used the regret lottery, which meant that ineligibles were included in the pool from which they chose. If a non-vaccinated person is selected, they will still be notified that they could have won, had they been vaccinated.
The lottery also increased the chances of winning some zip codes that had low rates of vaccination.
By the end of the lottery, 73,865 people were registered in the lottery.
The researchers found that zip codes where residents were 80 times more likely to win cash prizes, and residents were no more likely to be vaccinated than other zip codes.
“I’m not going to lie, it was disappointing,” Philadelphia Department of Public Health spokesman Jim Garrow told KYW. “We keep doing outreach and trying to find other incentive programs. For everyone, it might be something different.”
The researchers said two factors could have a better effect on the population, including higher financial reward, better marketing, and the start of the lottery sooner.
As of August 20, 78.8% of eligible adults had received at least one injection of the vaccine, while 64.4% had received the full vaccination.
Amidst a variable delta escalation, city officials are working to develop new ways to vaccinate more residents. The paper’s authors said they analyzed Philly Vax Sweepstakes to provide better information for future incentive programs.
