JEFF SMITH: Continues to promote that New York has been a leader in handling of the pandemic. He says the launch of the Excelsior Pass is the latest example. This so-called digital vaccine passport is the first of its kind. It's an app that will allow New Yorkers to display digital proof of a vaccination, through a barcode on their smartphones.

A secondary app will then allow businesses and other venues to scan those barcodes. It's designed to be a potential game changer in a post-pandemic world.

KATHRYN WYLDE: We can have entertainment. We can have nightclubs. We can go back to a New York-- or go forward, actually, to a New York-- that is the one that we recognize.

ANDREW CUOMO: You're going to see the number of vaccines coming to the state increasing. And as soon as we get those vaccines to this state, we are going to get them in arms.
