PHILADELPHIA — Philadelphia will be giving away cash prizes as part of a multiweek lottery to entice residents to get vaccinated for COVID-19.

Each of three drawings will award 12 prizes, with half being reserved for people in a designated under-vaccinated ZIP code.

Philadelphia’s first drawing on June 21 includes six $1,000 prizes, four $5,000 prizes and two $50,000 prizes. People living in the 19126 ZIP code in north Philadelphia will be awarded half the prizes in those categories. City officials say that ZIP code is one of the 20 least vaccinated in the city and was chosen at random.

Several states including Ohio, New York, New Mexico, Colorado, Oregon and Maryland are running financial incentive lotteries to increase the number of people seeking out vaccines.
