We call this type of immunity adaptive---> natural----> active immunity. Here how it works:
Adaptive immunity involves two classes of lymphocyte: B cells and T cells which work together in a coordinated system of adaptive immunity
B cells-antibody-mediated (humoral) immunity
T cells-cell-mediated (cellular) immunity
Adaptive immunity occurs in a series of stages
1. Recognition of antigen (flu virus)
2. Activation of lymphocytes
3. Effector phase (immune attack)
4. Decline of antigen causes lymphocyte death (homeostatic balance)
5. Memory cells remain for later response if needed
yes,you can get influenza by kissing,if Your immune system were weak against that virus
Flu viruses that people are not immune to.
T cells are the components of the immune system that coordinate immune defenses and kill infected cells on contact.
T cells produce cytokines, such as interferons and interleukins, that help enhance the immune response against virus-infected cells. They also release cytotoxic substances, like perforin and granzyme, which can directly kill infected cells. Additionally, T cells can activate other immune cells, like macrophages, to help eliminate virus-infected cells.
CD8 T cells kill infected cells by releasing proteins called perforins and granzymes. Perforins create pores in the infected cell's membrane, allowing granzymes to enter and trigger cell death. This process helps eliminate the infected cell and stop the spread of the infection.
The major histocompatibility complex (MHC) molecules are marker molecules on cells that the immune system uses to recognize pathogens. MHC molecules present fragments of pathogens on the cell surface to alert immune cells to the presence of the pathogen. This helps the immune system to target and eliminate infected cells.
When the body is infected with a pathogen, the immune system recognizes the foreign bodies and raises the temperature to try and kill of the pathogens. This causes a fever, which is an increase in body temperature above 98.6 degrees Fahrenheit.
Interferons are signaling proteins that are released by cells in the immune system in response to viral infections. They help to inhibit viral replication within infected cells by activating mechanisms that make the cell less hospitable to the virus, such as degrading viral RNA and proteins. Interferons also help to stimulate immune responses that target and eliminate virus-infected cells.
Macrophages, granulocytes, and lymphocytes are key components of the immune system that work together to locate, recognize, and eliminate pathogens. Macrophages and granulocytes use pattern recognition receptors to identify common features on pathogens, such as lipopolysaccharides or peptidoglycan, facilitating their engulfment and destruction through phagocytosis. Lymphocytes, particularly T cells and B cells, recognize specific antigens presented by infected cells or pathogens, leading to targeted immune responses: T cells can directly kill infected cells, while B cells produce antibodies that neutralize pathogens or mark them for destruction. Together, these immune cells coordinate a robust response to eliminate infections.
Cytotoxic T cells, also known as cyte cells, play a crucial role in the immune system's response to infection. These specialized cells are responsible for identifying and destroying infected cells in the body. By recognizing specific antigens on infected cells, cyte cells can target and eliminate them, helping to prevent the spread of infection and protect the body from harm.

You can't, the survivors you play as are immune to the disease the infected carry. So it is impossible.
