Dr. Dillaha said they are still not sure how long this type … The brief rise in body temperature during and right after exercise may prevent bacteria from growing. A vaccination is an example of active immunity. And the immune system recognizes when certain invaders are foreign and could be dangerous. Main advantage of active immunity is that the resistance is long-term. The two main mechanisms for this type of immunity are cell-mediated immunity and humoral immunity, which are both executed by lymphocytes. Consequently, immunity can be defined as the ability of an organism to fight against diseases and infections. This disorder is … Adaptive (Acquired) Immunity There are two types of immunity that the adaptive immune system provides, and they are dependent on the functions of B and T cells, as described above.
