T cell enhanced by BCG/TB is the key to fight against C19 and Dectin-2+TB/BCG may prevent the severe stage of C19, cytokine storm.
Don't care about antibodies. Let's care for innate immunity; T cell and macrophage. https://www.jsatonotes.com/2020/05/dont-care-antibodies-lets-care-innate.html
And here comes a groundbreaking paper that shifts people's attention to T cell from Karolinska, Sweden.
Robust T cell immunity in convalescent individuals with asymptomatic or mild COVID-19
I summarize the points of this paper. Please read them and check the charts below. There are SARS-CoV-2-specific memory T cellsSARS-CoV2-specific T cells were detectable in antibody-seronegative family members and individuals with a history of asymptomatic or mild COVID-19.While there are few SARS-CoV-2-specific memory T cells in blood donors of 2019, there are a substantial number of SARS-CoV-2-spe…
