Researchers from the Wellcome Sanger Institute, Newcastle University, University College London, University of Cambridge, EMBL's European Bioinformatics Institute (EMBL-EBI) and their collaborators within the Human Cell Atlas initiative, found raised levels of specific immune cells in asymptomatic people.

Vaccines created by UVA Health's Steven L. Zeichner, MD, PhD, and Virginia Tech's Xiang-Jin Meng, MD, PhD, prevented pigs from being becoming ill with a pig model coronavirus, porcine epidemic diarrhea virus (PEDV).

An international team of researchers unexpectedly found that a biochemical pathway, known as the immune complement system, is triggered in lung cells by the virus, which might explain why the disease is so difficult to treat.
