Infection with common cold coronaviruses can trigger broad cross-immunity against SARS-CoV-2 protein

NEW - Infection with common cold coronaviruses can trigger broad cross-immunity against COVID, research by the University Medical Center Hamburg-Eppendorf in Germany finds. In a new study, the team now compared the specific T cell response to SARS-CoV-2 RNA-dependent RNA polymerase—a non-structural protein—in blood samples of COVID-19 patients and of subjects who had never had COVID, including pre-pandemic samples. In all samples the researchers detected a broad immune system T cell response. The T cells found in the samples from people who had never been infected with SARS-CoV-2 therefore presumably arose in response to an earlier infection with other common cold coronaviruses and cross-reacted in the tests with the SARS-CoV-2-poymerase protein. https://idw-online.de/de/news814454 |

It would be interesting to correlate the rate of natural immunity with the parental status of the subjects. I'm sure that immunity rates are much higher among those who have children in school, especially young children... The kind coming back from school with the sniffles and sneezing in your face when you hug them

That’s not because the variants are less robust. It’s because the immune responses are higher," Barouch said. |

But there is viral attenuation....unless you've been blasting your immune system with the mrna experiment |
