New research from scientists at Washington University School of Medicine in St. Louis suggests that the immune systems of COVID-19 patients can't do enough to protect them from the virus.

A popular theory has it that patients' immune systems get so revved up fighting the virus that, after several days, a so-called cytokine storm ensues, resulting in potentially fatal organ damage, particularly to the lungs. But new findings from a team of researchers led by Richard S. Hotchkiss, MD, a professor of anesthesiology, and Kenneth E. Remy, MD, an assistant professor of pediatrics, have found that many patients get very sick because their immune systems can't do enough to protect them from the virus. They're suggesting that rather than trying to dampen the immune response, a better treatment strategy for COVID-19 would involve boosting immunity.
