China and South Korea have demonstrated that with very intensive interventions viral transmission can be pushed down to low levels2, but this will not offer a permanent solution in the foreseeable future. Without herd immunity, either through natural infection or vaccine-induced, the COVID-19 epide...
you may be wondering how long you will have immunity from the coronavirus. Earlier in the pandemic, most people assumed that getting infected had at least one upside: that you would be protected against future encounters with the virus. But as the latest wave heads toward the Western region o...
With most people in China having been infected with COVID-19, herd immunity has been reached and the transmission ability of the epidemic gradually weakens, said Fang Bangjiang, a doctor from Longhua Hospital Affiliated with Shanghai University of Traditional Chinese Medicine, on Friday. Data relea...
Immunology is part of the process of clinical evolution, but there are some questions around immunity-based protection: (1) why some infected people have only mild symptoms of the disease or are asymptomatic; (2) why delayed and weak antibody responses are associated with severe outcomes; and ...
Herd immunity is when a large part of the population is immune to a specific disease. Find out how it affects infectious diseases like COVID-19.
T cells and B cells also both play an important role in long-term protective immunity. After an infection, certain long-lived T cells and B cells become primed to recognize specific proteins on the virus right away. This time, if they see these same viral proteins, they get right to work...
memory B cells, should be primarily located in peripheral lymphatic tissues such as lymph nodes and the spleen, while only a few mature B cells would exist in the circulation. Therefore, the B-cell population in PBMCs...
我们描绘了出院后3至6个月健康对照组和感染COVID-19后患者呼吸道和外周血中的免疫蛋白质组学情况。与健康个体相比,感染COVID-19后患者的呼吸道(但不是血浆)蛋白质组异常,与细胞凋亡、组织修复和上皮损伤相关的蛋白质浓度升高。呼吸...
发表期刊:Immunity 影响因子:43.474 发表时间:2022 01、背景 继发性感染导致脓毒症是COVID-19重症感染的常见情况,然而,在急性感染期间,凝血病变等病理的根本原因和降低死亡率的机制尚不清楚。今天给大家带来一篇相关的研究,文章首先利用不同小鼠模型(n=6)进行组织学研究、免疫荧光成像以及病理研究,以研究肌动蛋白和...
FullText The vast majority—more than 96%—of people aged 16 years or older in the US had SARS-CoV-2 antibodies by September 2022, including about 48% who had “hybrid immunity,” or immunity derived from both vaccination against and infection with the virus. People who were unvaccinated we...
