Vaccination of animals for the prevention of infectious diseases has been practised for a number of years with little change in product composition. Recent advances in molecular biology, pathogenesis and immunology have laid the groundwork for the development of a new generation of veterinary vaccines based on pure subunits as well as live vectored bacteria and viruses. Along with novel methods of antigen preparation, the use of new adjuvants and delivery systems will permit targeting of the appropriate immune response as well as offering flexibility in terms of vaccination protocols. These new technologies are also being applied to the development of vaccines to enhance animal productivity and to control reproduction.  相似文献

Veterinary vaccinology is a very interesting and rapidly developing field. In fact veterinary vaccines are not only used for the prevention of infectious diseases in the animal health sector, but also help to solve problems of public health, to reduce detrimental environmental impact of the use of some veterinary drugs and prevent the emergence of resistance of micro-organisms or parasites. After a short introduction, this paper will deal with the use of vaccines for animal health and welfare, including new developments in the veterinary field such as marker vaccines and vectored vaccines, the special case of equine influenza-inactivated vaccines and the use of veterinary vaccines in public health. The conclusions will analyse the reasons as to why develop veterinary vaccines and the obstacles to their development.  相似文献
