“President Donald Trump has been touting chloroquine and hydroxychloroquine since March as effective treatments for COVID-19. He even took hydroxychloroquine as a prophylactic measure for two weeks in May.
Last week, when the president was hospitalized for a COVID-19 infection, his physicians listed the medications with which he is being treated. Hydroxychloroquine is notable by its absence.
Instead, the president has been aggressively treated with Regeneron Pharmaceuticals’ polyclonal antibodies. This combination of two monoclonal antibodies aims to block the coronarvirus from infecting cells, providing extra time for patients’ immune systems to ramp up their own natural defenses against the virus. While the treatment is still in clinical trials, preliminary reports suggest that it does substantially help to alleviate COVID-19 symptoms.”
