Mayor Bill de Blasio announced 75% of New York adults are vaccinated but said more has to be done. On Thursday, he announced another incentive to encourage more people to get their shots.

De Blasio believes that incentives are key to getting the vaccination rate up, saying sometimes people need motivation. That's why he announced that now New York City's public school PTAs can get in on the action.

PTAs can now join New York City's referral bonus program. Whenever they help to get a student or a family member vaccinated, they will receive $100 for every individual they sign up - with the families also receiving $100. The mayor says an incentive like this will help the education system.

So far, more than 80,000 New Yorkers have gotten their $100 incentive, which is around $8 million that has been paid out so far
