Revisiting the thirty years-old notions of resource-bounded immunity and simplicity, we investigate the structural characteristics of various immunity notions: strong immunity, almost immunity, and hyperimmunity as well as their corresponding simplicity notions. We also study limited immunity and simplicity, called k-immunity and feasible k-immunity, and their simplicity notions. Finally, we pr...

Immunity to malaria could be categorized broadly as antiparasite or antidisease immunity. While most vaccine research efforts have focused on antiparasite immunity, the evidence from endemic populations suggest that antidisease immunity is an important component of natural immunity to malaria. The processes that mediate antidisease immunity have, however, attracted little to no attention, and m...

Support for the concept of the development of immunity during the course of syphilis is avaiable in the literature. In experimental syphilis in rabbits, some immunity is present approximately 3 weeks after infection with Treponema pallidum. Resistance to re-infection increases to a maximum at approximately 3 months after infection. Termination of this state by penicillin treatment within this 3...
