Summary

To reach herd immunity for COVID-19, experts estimate that 70% of the population will need to be vaccinated. However, vaccination rates have begun to slow down in the United States. The investigators will partner with Philadelphia to launch a COVID-19 vaccination sweepstakes, in which residents will be eligible to win if they have received at least one dose of the COVID-19 vaccine prior to a given drawing. Drawings will be held every two weeks; multiple prizes of various sizes will be awarded in each drawing. Half of the prizes in each size category in each drawing will be awarded to residents of a zip code that is randomly selected from a pre-defined list of under-vaccinated zip codes (this zip code will be announced at the start of each 2-week drawing period), the other half will be awarded to residents outside of that selected zip code. The investigators will analyze vaccination rates in Philadelphia as compared with neighboring regions before, during, and after the specified time period, as well as analyze vaccination rates in the three selected zip codes compared to the other zip codes that could have been targeted (the residual set of under-vaccinated zip codes) to determine the effectiveness of the sweepstakes at encouraging vaccinations.
