New Study shows Potential of T-Cells in the fight against Covid-19


In my previous article, I reported on the 2 tests currently being undertaken in the UK following the Covid-19 outbreak, namely the Viral Test (PCR) and the Antibody Test – both of which I believe are questionable in their use and findings.



Having viewed many papers and scientific studies looking at T-Cell immunity this appears prima facie to be of far more importance – time to take a closer look.

On 14 August the Cell Journal (a peer-reviewed scientific journal) published a report stating that mild cases of coronavirus disease 2019 (COVID-19) can trigger robust memory T cell responses, even in the absence of detectable virus-specific antibody responses.

The authors say that memory T cell responses generated by natural exposure to or infection with SARS-CoV-2 – the virus that causes COVID-19 – may be a significant immune component to prevent recurrent episodes of severe disease.

New Study Shows 17 years of potential T Cell immunity in SARS-infected Patients

The latest research on T cells – white blood cells produced by the immune system to ward off infections through memory of past pathogens – show that even patients who never develop antibodies or have lost them over time retain T cell immunity that “remember” to fight off coronaviruses in the future.

Cross Cell Immunity

Researchers in Singapore conducted a study in May which has now been peer reviewed and published. The study provides new evidence for the theory that herd immunity could be achieved at approximately 20% infection rates thanks to T cell cross-immunity from other coronaviruses.

The study was conducted on 23 patients who recovered from SARS in 2003, it found that all 23 retained Memory T cells induced by the original pathogen which remained in their systems 17 years later.

They then studied 36 convalescent SARS-CoV-2 (Covid-19) patients and found that they had also produced similar T cells.

While SARS-CoV-2 is a new virus and distinct from SARS-CoV-1 (although reportedly contains a 79% genetic similarity), there is strong reason to believe that T cell memory protects from future relapses and would not be weaker or more short-lived than T cell memory from SARS-1.

The findings of this research shows that all those infected with SARS-Cov-2 will retain at least partial immunity to the virus.  This would likely mean, for many previously infected patients, that they would theoretically test positive again with a PCR test, but the T cells would ward off the systems and reduce their infective capabilities to transmit to others.

There is more good news – very few people in the west have been exposed to the 2003 SARS and would therefore not have that immunity, however, researchers have long suspected that there is cross-immunity from other coronaviruses – four of which are forms of the common cold.

Cross-immunity has been proven across other pathogens and was established during the H1N1 outbreak in 2009 when many people appeared to be immune, presumably, to prior outbreaks of seasonal H1N1 flues.

This harmonises with a previous study from the La Joya Institute of Immunology in California which shows such cross-reactive responses in 40%-60% of random blood donors.

This may also explain why so many people are found to be asymptomatic but never tested positive for antibodies. https://www.nature.com/articles/s41586-020-2550-z


It is clear with time and data that Covid-19 was not the plague it was made out to be by Global Governments and mainstream media and it would appear our immune systems (if in good shape) were more than capable of fending off this virus as we have seen with previous “pandemics”.

Worldometer the “go to” measurement of global Covid cases (as at 26/08/2020) outlines this beyond any reasonable doubt.
