Wall Street Journal is reporting Eli Lilly Inc. has high hopes that their “monoclonal antibody” to fight COVID-19 can finish human testing soon, go into mass production, and be in use much earlier than the first vaccines.

My guess is that getting a one hour long IV of these monoclonal antibodies will cost anywhere from one to five hundred times more than the cost of getting a traditional vaccine, but the antibodies start working immediately, whereas the vaccine takes 2 to 4 weeks. Good vaccines create both antibodies and T-cells.
