The action of phagocytes considered a nonspecific response because it is a response to any type of harmful substance with out any specificity.
Phagocytosis is a process in which a cell engulf any molecule using its plasma membrane. Phagocytes provide non specific defense mechanism as it the first line of defense of our body. our immune system has to tackle several types of foreign particles, Viruses, Bacteria and harmful proteins. This non specificity of action makes the response quicker than the specific

I am certain that the difficulties of maintaining a long-term immune memory to influenza viruses are due to the Antigenic shift from zoonotic sources.
The adaptive immune response is intiated when the DCs present viral antigens to the naive and memory T-lymphoctes. During an influenza infection, the antigens are acquired by the DCs through two different mechanism.
