Synopsis (short abstract) 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.

    Rational use of vaccination for control and prevention of H5 highly pathogenic avian influenza (EMPRES FOCUS ON) 2016

    Vaccination can play a valuable role in control, prevention and elimination of highly pathogenicity avian influenza (HPAI) viruses in poultry. However, risk of adverse consequences as well as concerns about availability of sufficient resources to conduct vaccination programmes often restrain countries from embarking on vaccination. This document discusses concerns regarding poultry vaccination for H5 HPAI, with the aim to facilitate decision making in affected countries or those at risk of H5 HP AI incursion. The document contributes to FAO’s Strategic Objective 5 by helping to increase the resilience of livelihoods to threats from HPAI.

    Poultry production in South East Asia has been challenged by various animal diseases threats including highly pathogenic avian influenza (HPAI), other emerging zoonotic influenzas and transboundary animal diseases (TADs). In order to mitigate the risk, the Food and Agriculture Organization’s Emergency Centre for Transboundary Animal Diseases (FAO-ECTAD) in collaboration with the United States Agency for International Development (USAID) and the Australian government is implementing the project “Evidence-Based Risk Management along the Livestock Production and Market Chain” in the region.
