An improved reverse genetics system for influenza A virus generation and its implications for vaccine production present an improved system for the generation of influenza viruses that allows the easy and repro ducible production of vaccine viruses in vero cells. Application of this system may be especially advantageous in situations of outbreaks of highly pathogenic avian influenza viruses.

Keeping poultry makes a substantial contribution to household food security throughout the developing world. It helps diversify incomes and provides quality food, energy, fertilizer and a renewable asset in over 80 percent of rural households. Small-scale producers are however constrained by poor access to markets, goods and services; they have weak institutions and lack skills, knowledge and appropriate technologies. The result is that both production and productivity remain well below potential and losses and wastage can be high.

Prion diseases are fatal neurodegenerative disorders caused by proteina-ceous infectious pathogens termed prions (PrP Sc ). To date, there is no pro-phylaxis or therapy available for these transmissible encephalopathies. Passive immunization with monclonal antibodies recognizing the normal host-encoded prion protein (PrP C ) has been reported to abolish PrP Sc infec-tivity and to delay onset of disease.

Poultry in 2006 our country has about 215 million children. Song epidemic of Highly Pathogenic Avian Influenza (HPAI) caused by H5N1 virus broke out in almost all provinces in the country from early 2004 to far as millions of birds have been destroyed. H5N1 epidemic has caused great impact both in terms economic and social area. The question arises: how to limit this dangerous disease and war translated by vaccine inoculation has to be a useful tool? This study aims to classify poultry production system with the obstacles encountered in each system, especially the risk of disease...

An illuminating example is the case of Rotashield, a rhesus reassortant rotavirus vaccine, which was introduced for routine use in the United States in the late 1990s. Within 9 months of its introduction, cases of intussusception were reported by the CDC to be temporally associated with the administration of the initial vaccine dose. This report led first to the cessation of the vaccine's use and subsequently to its withdrawal from the market and the discontinuation of its production.

Current recommendations also include influenza vaccine for routine annual administration to individuals with chronic illness at any age, to persons living in the same household as chronically ill individuals, and to all adults 50 years of age. Polyvalent pneumococcal polysaccharide vaccine is similarly recommended for adults ≥65 years of age and for all chronically ill persons.

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.

Risk Assessment Vaccines are considered safe when the risk of use is judged to be acceptable in relation to the benefits. For vaccines given to healthy individuals for diseases that are no longer common, acceptable risks are set at very low levels—indeed, far lower than for most medical products. However, "safety" does not and cannot ever mean "zero risk." The determination of safety is thus based on a scientific assessment of the data and a considered judgment of all the issues involved, including benefits and risks.

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).
