Finally a 2850 study on tcells. The quote below is from the telegraph and the official document is linked below.
"A quarter of people may already be immune to coronavirus even though many of them have never been infected, a new study by Public Health England (PHE) suggests.
Over the past few months, researchers have followed nearly 2,850 key workers from the police, fire and health services to gauge levels of immunity to the virus.
They discovered that, by June, one in four had high levels of T-cells which recognised Covid, suggesting they had some level of protection against the virus – but nearly half had never been infected.
Researchers believe they probably picked up immunity from similar coronaviruses such as those that cause the common cold. In the four months of follow-up, nobody with a high T-cell count became infected with Covid, suggesting they were protected against it"
Dr Peter Wrighton-Smith, the CEO of Oxford Immunotec, the company that developed the T-cell test for trial, said it showed antibody testing alone may underestimate the number of people already immune to the virus.
"About 1/4 of the keyworker population studied had high levels of T cells which recognised SARS-CoV- 2 in their blood when they joined the study in June 2020. By 'high levels' we mean levels similar to those seen in people who have had COVID-19 disease. However, about half the people with high levels of T cells in their blood have not had COVID- 19, as far as we could tell- the cells were probably there because of previous infection with coronaviruses other than SARS-CoV-2.
Importantly, in our study people with higher levels of circulating T cells appeared to be protected from COVID-19 in the four months after recruitment in June 2020. This applies both to people who have been previously infected with COVID-19, and to those who had not".
