"The president received a single 8 gram dose of Regeneron's polyclonal antibody cocktail as a precautionary measure, according to a memo from White House physician Dr. Sean Conley. The antibody cocktail is being studied in four late-stage clinical trials and its safety and efficacy have not been fully evaluated by any regulatory authority, the company said on its page.

The president also has been taking zinc, vitamin D, famotidine, melatonin and a daily aspirin, Conley said."
