More evidence that the SARS-CoV-2 is similar to the common cold virus and thus fairly harmless!
"The team determined that all of the ill patients had fewer overall T cells than the healthy volunteers, which was consistent with earlier findings from other groups. All patients had helper T cells and eight of 10 had killer T cells that targeted SARS-CoV-2 proteins. These reactive T cells showed up within about 10 days of symptom onset in the patients. The strongest responses were to the SARS-CoV-2 spike protein, but cells responded to membrane and nuclear viral proteins, too. ... The study authors reported that two healthy controls also had circulating SARS-CoV-2-fighting T cells, something that showed up in healthy controls in the study of milder cases of COVID-19 in May. “A likely explanation is that this is reflective of exposure to common cold coronaviruses which . . . are cousins of SARS-CoV-2,” ..."
SARS-CoV-2-Reactive T Cells Found in Patients with Severe COVID-19 | The Scientist Magazine® A small subset of uninfected people also had SARS-CoV-2-fighting T cells, a finding that scientists are still trying to figure out.
