Assessing the Impact of Vaccine Lotteries on COVID-19 Vaccination Rates in the United States in 2021.

We assessed the impact of COVID-19 vaccine lottery programs on COVID-19 vaccination coverage using Centers for Disease Control and Prevention‒reported first-dose vaccination administration rates for the population aged 18 years and older for 19 states that adopted lottery-based incentive programs. We did not find evidence of increased first-dose vaccination rates following lottery announcements across participating states and, therefore, find little justification for the use of COVID-19 vaccination lotteries to increase vaccination rates.
