| | Basic Principles of Specific Immunity and Immunization |
 | | This is because innate immunity refers simply to the inability of many organisms that have not evolved to be, for example, human pathogens, to cause disease in (again, for example) humans because of the absence of mechanisms necessary to be invasive in humans | | | Another way of defining specific immunity is that it is a means by which a body defends itself against the presence of specific antigens associated with, for example, pathogens | | | Naturally acquired immunity is that immunity acquired upon exposure to a specific pathogen particularly in the course of an infection/disease |

| | Acquired immunity is when the body is exposed to various antigens and builds a defense that is specific to that antigen. | | | For example, an individual who has had chickenpox is immune to getting chickenpox again. | | | Your immune system includes barriers that keep harmful materials from entering your body. |

| | Yet, the two well-characterized forms of immunologic response—humoral immunity (HI) and cell-mediated immunity (CMI)—do not seem to be effective against many retroviruses (reviewed in 25). | | | From some of the statements regarding the nature of CAF, it could be interpreted that molecular immunity may be similar to so called transfer factor (TF), described in the old immunology literature. | | | This focus is due largely to history and momentum—HI and CMI are two well-studied and well-understood immunologic phenomena, and agents stimulating these responses have led to many successful vaccines in the past. |

| | Fortunately, immunity is a basic fact of nature; unfortunately, we take it for granted. | | | Immunity is the ability of an animal to resist disease. | | | In reality, immunity culminates from the activity of a very complex and intricate system of the body - the immune system; a system that we can to some extent enhance and manipulate to provide various degrees of protection against most disease-causing bacteria and viruses. |
