Mayor Bill de Blasio announced Tuesday that New York City has achieved a milestone in the battle against COVID-19.

Since the vaccination rollout began, he said the city has now administered 2 million vaccines. De Blasio described the vaccine as shots of hope in the fight against coronavirus.

The mayor is hopeful that the five boroughs are now on track to have 5 million residents vaccinated by June. De Blasio said though that to reach this goal will require the participation of multiple partners.

De Blasio said supply is key in order to roll out the vaccine as quickly as possible and to ensure disparities can be fought citywide. He's calling on the federal government and pharmaceutical companies to join in the fight to continue the process.

De Blasio's call comes as Johnson and Johnson's single dose vaccine received Food and Drug Administration approval for emergency use, joining the Pfizer and Moderna vaccines in the fight against COVID-19.

As de Blasio continues his efforts, he announced a new vaccination site would be coming to Co-op City on Thursday with the goal to reach New York residents in hard hit areas.

"Co-op City has not had its own vaccination site until now. Today, we announce that a new site will be open on Thursday in Co-op City, and let's face it, the Bronx has been hard hit by the COVID crisis," de Blasio said.
