The Department of Agriculture (DA) has stressed the importance of strict biosecurity measures and early reporting of hog farmers following an incident involving the controlled administration of the African Swine Fever (ASF) vaccine. Five vaccinated pigs died nine days after receiving the vaccine, with further investigation revealing that the animals had an existing respiratory illness that was not reported prior to the vaccination. Blood tests confirmed that the pigs were negative for ASF before vaccination.
The immunity levels of pigs typically remain at around 40% within 7-14 days after receiving the ASF vaccine. It takes approximately 28 days for the vaccine to fully activate and provide 90-95% immunity. In this particular case, the pigs’ already weakened immune systems, coupled with external factors such as poor biosecurity practices, contributed to their deaths. This highlights the critical need for farmers to adhere to proper biosecurity protocols and to report any health issues promptly.
DA Assistant Secretary for Swine and Poultry Dr. Constante Palabrica reiterated that strict biosecurity and reporting of any symptoms is essential to safeguarding the health of the entire swine population. ” “Effective vaccine administration must be complemented by strict biosecurity measures. Both are crucial in preventing the spread of ASF. Furthermore, early and honest reporting allows us to take swift action, ensuring that vaccinations are effective and protecting not just the vaccinated pigs but the entire herd from potential outbreaks,” Dr. Palabrica stated.
Agriculture Secretary Francisco P. Tiu Laurel, Jr. echoed the need for vigilance among farmers in following protocols. “This incident is a reminder that vaccines are a crucial tool, but they must be part of a broader strategy that includes accurate health reporting and strict biosecurity measures. We remain committed to supporting our hog farmers and ensuring the recovery of our swine industry, but cooperation at all levels is key to making this effort successful.”
Despite this concern, the DA remains hopeful that the controlled vaccine administration will lead to a viable solution to ASF. However, they cautioned that farmers must follow guidelines to protect their animals and help control the spread of the virus. The DA is working closely with local government units and the private sector to strengthen monitoring and reporting systems as part of the comprehensive effort to revitalize the swine industry.
As of now, the DA continues to explore additional vaccine suppliers and complementary measures to ensure the sustainability of the hog industry and protect the livelihoods of farmers across the country. ### (Photo by Jay Morales, DA-OSEC)
