This video explains how cells process virus proteins so that T cells can recognize infected cells. In addition, he explains that the type of T cells responds by attacking infected cells for destruction and what T cells respond helping other immune system cells to recognize that the virus is present and set up an answer. [The video has no sound.]
Infected cells and innate immune system cells process virus proteins. This also happens with vaccines. Virus protein is processed in small fragments, called peptides. When those peptides are shown on the surface of a cell and are recognized by the immune system, antigens consulted are consulted. You can make many different peptides from a single virus protein. Therefore, there are many possibilities to train the T -system cells of the immune system to recognize the infection, even if the mutations borders the time that a person is exposed for the first time to the virus or vaccinated and the time that the person is exposed again.
