Ultra-cold freezers are ready to store Pfizer's coronavirus vaccine at Hackensack University Medical Center (HUMC).

HUMC President and Chief Hospital Executive Mark Sparta says the hospital's highest risk frontline workers will get the vaccine first.

"We were really concerned that we wouldn't have access to the vaccine for the frontline health care workers until at least the middle or end of 2021," Sparta says. "But the industry mobilized and within a period of nine to 10 months is something that typically takes five to 10 years to develop."

Recipients will get their second dose of the vaccine 20 to 21 days after the first.

Then after 8 to 10 weeks, they're expected to develop immunity to the virus.

The hospital network expects to give the vaccine to the public by mid to late February.
