    Highly pathogenic avian influenza (HPAI) is a zoonotic disease that can affect both poultry and humans. Since 2005, the Vietnam government has implemented a national vaccination campaign to prevent the spread of avian influenza (AI). In 2021, the first outbreak of HPAI H5N8 was reported in a chicken farm in Quang Ninh province. To gain a comprehensive understanding of the chain and its relevance to HPAI vaccination in various aspects, and to identify and comprehend the stakeholders involved in the AI campaign and their roles within the vaccine supply chain. A cross-sectional study was conducted from Nov-2021 to Jan- 2022. We purposively selected 114 participants, including 71 poultry farmers using HPAI vaccines, 16 veterinary drug store owners, 18 commune animal health workers (CAHWs), 8 staff from the Centers for Agricultural Services (ATSCs), and one vaccine distributor who were interviewed face-to-face using a structured questionnaire. Three HPAI vaccines (H5N1 clade 1 & 2.3.2.1, H5N1 clade 2.3.4, and H5N1 clade 2.3.2.1b) were used. Distributors stored vaccines at the required temperature and transported them in appropriate vehicles. Vaccines remained in the supply chain for 3–5 months within their 12-month shelf-life period. The free government vaccination campaign, implemented by CAHWs, and administered by the ATSCs, reached 61% of small-scale poultry farms with a 1.19% vaccine wastage rate. Large-scale poultry farms followed the national campaign but paid a fee for the vaccines. We recommend expanding the support for AI vaccination to increase the vaccination rate among large-scale poultry farms, selecting higher efficacy seed vaccines, and that smaller dose vaccine vials are available for cost-effective vaccination.

    Since its emergence in early 2004, Highly Pathogenic Avian Influenza (HPAI) caused by H5N1 has caused global concern, threatening both animal and human health.Viet Nam has been one of the countries worst affected with major impacts of the disease on poultry production, livelihoods and human health. FAO was established in Viet Nam in 1978. However following the onset of the disease, the Emergency Centre for Transboundary Animal Diseases Operations (ECTAD) was set up using FAO’s own finances to st art the programme. FAO works regionally and nationally to combat avian influenza in close collaboration with governments, national and international partners, bringing together technical expertise in socioeconomics, disease control, farming systems, agricultural and pro-poor policy, communications and extension. With the strong support and collaboration of the Government of Viet Nam FAO has provided technical and operational guidance for the control programme against HPAI and other major disease s such as foot and mouth disease and classical swine fever through the generous funding of several donors. In addition, to specific donor funded projects, the World Bank and the Government selected FAO to provide technical leadership and guidance to the Viet Nam Avian and Human Influenza Control and Preparedness Project (VAHIP) through the provision of technical advisers and specific expert consultancy services. The country team also receives support from the FAO regional and headquarters pool o f technical and operational resources, when required. In coordination with the World Organization for Animal Health (OIE), the World Health Organization (WHO) and United Nations System Influenza Coordinator (UNSIC), FAO has provided significant support to the Government of Viet Nam for the Hanoi pre-technical meeting and Inter-Ministerial Conference on Animal and Pandemic Influenza (IMCAPI) in April 2010.
