"It's like a supercharged immune system."

Dr. Ron Elfenbein, who treated COVID patients with monoclonal antibody infusions, breaks down what the drug actually is and how it differs from a vaccine.

A vaccine trains your body to build its own antibodies over time. A monoclonal antibody treatment skips that step entirely, giving you an already-made antibody through an IV infusion.

Elfenbein says patients would often start recovering right away.
