Overview of research and development of trivalent vaccines for waterfowl viral diseases

Yu-Hua Shih

Abstract

  The waterfowl trivalent viral vaccine is a multivalent vaccine containing live attenuated goose waterfowl parvovirus, Muscovy duck parvovirus, and duck hepatitis A virus. This multivalent vaccine could help prevent goose waterfowl parvovirus, Muscovy duck parvovirus, and duck hepatitis A virus infections. Ducklings infected with these diseases can exhibit high morbidity and high mortality rates, which will then result in stunted growth and potentially serious economic losses. Immunization of breeders with vaccines, to produce maternally derived antibodies for duckling protection, is a viable epidemic prevention strategy for these diseases. Commercially available monovalent vaccines typically use duck or chicken embryo eggs as vaccine proliferation materials, which can be influenced by a variety of factors. These vaccine strains are attenuated and proliferated in tissue culture, which bypasses the use of embryonic eggs. Furthermore, multivalent vaccines reduce the amount of labor required during administration while at the same time reducing animal stress induced by multiple vaccinations. AHRI has completed laboratory research and development experiments for this trivalent viral vaccine for waterfowl . In 2018 alone, AHRI produced 400,000 doses of this vaccine which were also used in field trials. This vaccine will provide for a new and more efficient vaccine selection for the duck industry.

Functional Overview of the Technical Service Office

Abstract

The functions provided by the Technical Service Office are extremely complex. In general, its current load can be categorized as: (1) reception and processing of documents/emails ; (2) management of the library as well as editing and publication of technical reports; (3) management and application of research and development results; (4) arrangement of veterinary continuing education and training, conferences, meetings, and the reception of various domestic and foreign visitors; and (5) management of general affairs and other occasional missions which cannot be categorized as the responsibilities of other divisions of this institute. In today’s talk, the daily functions of the Technical Service Office is introduced and analyzed, as we share our experience working with such a complex set of diverse tasks.
