Ivermectin works even better. But DeSantis has to use something that is FDA approved. It's up to the FDA to approve already known medications, and of course they didn't - approving a drug means invalidating the emergency approvals for the vaccines. The monoclonal antibody cocktails were especially made for C19, so the FDA was forced to consider them for approval. They dragged it out, demanding one trial after another, but the results were so overwhelming that they finally had to approve it. They have found a trick to avoid the invalidation of the vaccine approvals: They approved the antibodies only for "high risk" patients.
