T-cell Covid immunity 'present in adults six months after first infection'

[Northerner]

Cellular (T-cell) immunity against the virus that causes Covid-19 is likely to be present within most adults six months after primary infection, with levels considerably higher in patients with symptoms, a study suggests.

The data offers another piece of the puzzle that could be key to understanding whether previous Sars-CoV-2 infections – the virus behind Covid-19 – can prevent reinfection, and if so, for how long.

The study, led by the UK coronavirus immunology consortium, evaluated 100 non-hospitalised healthcare workers in March and April after antibody responses were detected in them. It is yet to be peer-reviewed.

It is the first study to offer data on T-cell levels six months after infection in people with mild or asymptomatic disease that is likely to represent the majority of infections, the authors say.

I have covid mid march and had a blood test last week that showed still present! very strange - lost my taste buds etc. still not totally back to normal

That report is exactly what I said on another thread. No surprise to me at all. And the presence of that immunity doesn't mean the infection is still present. My T-cells can remember me having measles, rubella, pertussis, and can remember my immunisations against polio and smallpox.

Admittedly, those T-cells are sitting around doing sod all at the moment, but they are ready and waiting. Wouldn't like to be the T-cell ready for a smallpox attack. Nothing worse than having your job taken away from you...
