The Urgent Need for a Japanese Encephalitis Virus Vaccine in Australia’s Pork Industry
The Australian pork industry, valued at $6 billion, faces a significant threat from the Japanese encephalitis virus (JEV). For three consecutive years, stakeholders have been waiting for a vaccine to curb the virus, which has already claimed nine lives since 2021. The industry’s demand for a solution is urgent, with the virus causing reproductive issues in sows and costing millions in damages.
Vaccine Development and Delays
Despite existing vaccines for humans, two pig vaccines developed by the University of Queensland and Apiam Animal Health have yet to clear federal approval. Chris Richards, CEO of Apiam Animal Health, reported that while their application passed preliminary assessment quickly, they have been waiting six weeks for further updates. Richards emphasized their ability to vaccinate 50,000 sows swiftly if granted emergency approval.
Dr. Jody Peters from the University of Queensland highlighted that their vaccine shows promising results in safety and effectiveness. However, regulatory bodies are yet to finalize their approval. “We have sufficient data, but the decision lies with the regulators,” Dr. Peters remarked.
The Struggles of Farmers
Farmers, urged to rely on mosquito control measures, feel neglected and desperate for a vaccine breakthrough. Laurie Brosnan, director of Betta Pork, described their extensive yet costly measures to protect against JEV, underscoring the inadequacy of current measures without a vaccine. Brosnan expressed frustration, stating that the industry feels forgotten amidst political distractions.
Expert Opinions on Future Prospects
Australian Pork’s chief executive, Margo Andrea, reiterated that JEV is a priority concern, with the previous outbreak costing millions and impacting operations across states. She advocated for continued efforts to secure a vaccine to protect herds and support producers.
The Growing Need
The need for a commercially available vaccine is becoming more pressing. Recent environmental conditions with flooding have increased mosquito populations, heightening the risk of JEV outbreaks. “The approval process delays are frustrating, but I remain hopeful for a future solution,” said Dr. Peters.
