“You’re going to see a very, very rapid expansion, and as soon as vaccine comes in, it’s going to get distributed, it’s going to get used very quickly,” the mayor said.

“We’re going to vaccinate the whole hospital in three weeks,” added Dr. Mitchell Katz, president and CEO of Health + Hospitals. “Everyone in every single unit.”
