Hi It' sKarol Sikora Some very exciting news, just yesterday, again from the karolinsky institute in stockholm sweden, showing that T cells are absolutely vital in our immune system. We tested all 200 staff in our cancer centres at the Rutherford and only 5.4% were actually positive for antibodies, and yet some of them lived together, and one was positive for antibody and one was negative, so there must be another component in the immune system, and that's what this paper shows. They took people recovered, measured antibodies in many there were no antibodies, and yet they showed that powerful T-cell systems are in place. So it means that instead of having just 5% of people infected, there'd be a huge number more, who are defending themselves by T-cell responses. Not only that, the T-cell system works against the previous 2 corona viruses, the sars and the mers, against which many of us have been infected, and many of us have immunity which will cross over to COV-2. So, I think it's good news, we're understanding more about the immune system, we've got to stick with it, do all the precautions necessar,y nad htere might be an outcome, a test if you've been infected and developed T-cell immunity.
