说得就是免疫T细胞:例如这里, “T cells, they cannot prevent infection,” said Lanier. “The only way a T cell can recognize you have an infection is after a cell has been infected.” Helper T cells are another important white blood cell variety. They spur the production of antibodies by a different group of white blood cells called B cells. B cells form in bone marrow and then migrate to lymph nodes or the spleen. After an infection or a vaccination, some B cells and T cells stick around, becoming memory B cells and T cells. They sit idle, sometimes for decades, waiting to see if a pathogen returns. If it does, they can quickly reactivate. 再如这篇研究:https://www.science.org/doi/10.1126/science.abm0829 mRNA vaccines induce durable immune memory to SARS-CoV-2 and variants of concern 很多研究都证实了mRNA 疫苗产生了长期免疫T细胞,你却视而不见,只相信你自己。 These findings demonstrate multicomponent immune memory after SARS-CoV-2 mRNA vaccination, with memory B and T cell responses remaining durable even as antibodies decline. Immune memory was resilient to VOCs and generated an efficient recall response upon antigen reexposure. These durable memory cells may be responsible for continued protection against severe disease in vaccinated individuals, despite a gradual reduction in antibodies. |
