Man, I look at the business news, and I see an article on T-cells, do these folks not know that some people are triggered by that!!!! The T-Cell Covid Cavalry Two studies suggest this line of defense reduces Omicron’s severity. https://www.wsj.com/articles/the-t-cell-covid-cavalry-antibodies-vaccines-omicron-11640906490
T cells from common colds cross-protect against infection with SARS-CoV-2 A new study, published in Nature Communications and led by Imperial College London researchers, provides the first evidence of a protective role for these T cells. While previous studies have shown that T cells induced by other coronaviruses can recognize SARS-CoV-2, the new study examines for the first time how the presence of these T cells at the time of SARS-CoV-2 exposure influences whether someone becomes infected. The researchers also say their findings provide a blueprint for a second-generation, universal vaccine that could prevent infection from current and future SARS-CoV-2 variants, including Omicron. https://medicalxpress.com/news/2022-01-cells-common-colds-cross-protect-infection.html
T-cells. Don't leave home without em. Persistent T cell response to omicron after infection and vaccination The omicron variant can partly evade the antibody response provided by vaccination or infection with previous variants of SARS-CoV-2. However, T cells still recognize omicron, scientists at Karolinska Institutet in Sweden report in a study published in the journal Nature Medicine. https://medicalxpress.com/news/2022-01-persistent-cell-response-omicron-infection.html
