Living in New York and not vaccinated? A new effort starting Friday will pay $100 for New Yorkers to get the COVID-19 vaccination. 

New York City Mayor Bill de Blasio announced Wednesday that the city will give cash incentives to residents who make an appointment at a city-run vaccination site.

"I personally believe that the guarantee that right then and there you're going to be rewarded, I think that's going to make a big difference to people," de Blasio said at a press conference.

The city said the payment will come in the form of a $100 prepaid debit card while waiting during the post-vaccine observation period, or they can receive it through the mail.

De Blasio was asked about those who already were vaccinated. He thanked people for “doing the right thing” but clarified the incentive is about getting the 41% of people vaccinated that have been holding out.

"What's in all of our interest is to get every single additional person vaccinated,” he said.

De Blasio also recently mandated that all state hospitals and all patient-facing health care workers must get vaccinated.

The city has made other efforts to get people vaccinated. The city offered free tickets to Yankees games and May 7 to June 6 and free Mets games from May 24 through June 17.

Along with the first week of July, he was offering free two-day passes to any state park.

The state has currently administered 9 million doses of the COVID-19 vaccination and 59% of the city’s population has been vaccinated.
