  • It has been recognized for many years that states of nutrient deficiency are associated with an impaired immune response and with increased susceptibility to infectious disease. In turn, infection can affect the status of several nutrients, thus setting up a vicious circle of under nutrition, compromised immune function and infection.

  • Approaches to Passive Immunization Passive immunization is generally used to provide temporary immunity in a person exposed to an infectious disease who has not been actively immunized; this situation can arise when active immunization is unavailable (e.g., for respiratory syncytial virus) or when active immunization simply has not been implemented before exposure (e.g., for rabies). Passive immunization is used in the treatment of certain illnesses associated with toxins (e.g.

  • As noted above, the number of licensed vaccines and the strategies for their best use change constantly as new products, new indications, and new information become available. The Advisory Committee on Immunization Practices (ACIP) regularly amends immunization recommendations to reflect the evolution of vaccines and vaccination policy in the United States.

  • Harrison's Internal Medicine Chapter 116. Immunization Principles and Vaccine Use Principles of Immunization The immune system, composed of a variety of cell types and soluble factors, is geared toward the recognition of and response to "foreign" substances termed antigens. Vaccines convey antigens from living or killed microorganisms (or protein or carbohydrate molecules derived from these antigens) to elicit immune responses that are generally protective but can occasionally backfire and cause harm to the recipient.

  • Table 116-4 Standards for Immunization Practice Child and Adolescent Immunization Practice 1. Immunization services are readily available. 2. Vaccinations are coordinated with other health care services and provided in a "medical home" when possible. 3. Barriers to vaccination are identified and minimized. 4. Patient's costs are minimized. 5. Health care professionals review the vaccination and health status of patients at every encounter to determine which vaccines are indicated. 6. Health care professionals assess for and follow only medically accepted contraindications. 7.

  • The Immune Response While many constituents of infectious microorganisms and their products (e.g., exotoxins) are or can be rendered immunogenic, only some stimulate protective immune responses that can prevent infection and/or clinical illness or (as in the case of rotavirus) can attenuate illness, providing protection against severe disease but not against infection or mild illness. The immune system is complex, and many factors—including antigen composition and presentation as well as host characteristics—are critical for stimulation of the desired immune responses (Chap. 308).

  • To evaluate the immune activation and reactive oxygen species scavenging activity of Cordyceps militaris polysaccharides (CMP) in vivo, 90 male BALB/c mice were randomly divided into six groups. The mice in the three experimental groups were given cyclophosphamide at 80 mg/kg/d via intraperitoneal injection and 17.5, 35, or 70 mg/kg body weight CMP via gavage. The lymphocyte proliferation, phagocytic index, and biochemical parameters were measured.
