Yet another study confirming both B and T cell long lasting and stable immunity in Covid-19 recovered patients. Those who have had Covid-19 DO NOT NEED the vaccine. Yet in many countries they are being threatened with #GreenPass, which can only be kept “Green” with regular doses of vaccine.

Immunodominant T-cell epitopes from the SARS-CoV-2 spike antigen reveal robust pre-existing T-cell immunity in unexposed individuals | Scientific Reports

The COVID-19 pandemic has revealed a range of disease phenotypes in infected patients with asymptomatic, mild, or severe clinical outcomes, but the mechanisms that determine such variable outcomes remain unresolved. In this study, we identified immunodominant CD8 T-cell epitopes in the spike antigen using a novel TCR-binding algorithm. The predicted epitopes induced robust T-cell activation in unexposed donors demonstrating pre-existing CD4 and CD8 T-cell immunity to SARS-CoV-2 antigen. The T-cell reactivity to the predicted epitopes was higher than the Spike-S1 and S2 peptide pools in the unexposed donors. A key finding of our study is that pre-existing T-cell immunity to SARS-CoV-2 is contributed by TCRs that recognize common viral antigens such as Influenza and CMV, even though the viral epitopes lack sequence identity to the SARS-CoV-2 epitopes. This finding is in contrast to multiple published studies in which pre-existing T-cell immunity is suggested to arise from shared epitopes between SARS-CoV-2 and other common cold-causing coronaviruses. However, our findings suggest that SARS-CoV-2 reactive T-cells are likely to be present in many individuals because of prior exposure to flu and CMV viruses.

“The Spike protein is itself toxic and dangerous for humans,” says Professor Bridle

“We made a mistake”. In a recent interview with journalist Alex Pierson, Professor Byram Bridle, a specialist in viral immunology, says this new research and work has led him to make important discoveries about the virus and in particular the Spike protein. This protein is the one that has been the subject of much work, particularly on messenger RNA vaccines.

The “new virus”. I predicted pre existing immunity to it ages ago. Both B and T cells immunity, even cross reactive, is now a fact. The mass vaccination programme makes no sense, unless other reasons for it are taken into account.
