Porcine Vaccines: India Ramps Up Efforts to Safeguard its Pig Industry

The health of India's pig industry, a crucial component of its rural economy and food security, is increasingly reliant on effective vaccination strategies. With the rising prevalence of devastating diseases like African Swine Fever (ASF) and Classical Swine Fever (CSF), the development, accessibility, and widespread adoption of porcine vaccines are making significant headlines across the nation.

Breakthrough in Classical Swine Fever (CSF) Vaccine

In a landmark achievement for Indian veterinary science, the Indian Institute of Technology-Guwahati (IIT-Guwahati) recently transferred a pioneering recombinant vector vaccine technology for Classical Swine Fever (CSF) to BioMed Pvt. Ltd. This first-of-its-kind recombinant virus-based vaccine, specifically designed for pigs and wild boars, fills a critical gap in India's fight against CSF, a highly contagious disease with high mortality rates. This development, rooted in collaborative research between IIT-Guwahati and Assam Agricultural University, underscores India's commitment to self-reliance in animal health solutions. The vaccine is currently in the process of obtaining its test and analysis license for commercial rollout.

The Ongoing Challenge of African Swine Fever (ASF)

While the CSF vaccine offers significant hope, the shadow of African Swine Fever (ASF) continues to loom large. First confirmed in India in Arunachal Pradesh and Assam in early 2020, ASF has since caused widespread devastation to pig populations. A crucial point highlighted in news reports is that, globally, there is still no effective commercial vaccine widely available against ASF. The Pirbright Institute is conducting animal trials for a vaccine candidate against ASF, which holds promise. This lack of a vaccine makes stringent biosecurity measures the primary defense against the disease, a strategy consistently emphasized by the Indian Veterinary Research Institute (IVRI) and state animal husbandry departments. Recent limited introductions of live attenuated ASF vaccines in Southeast Asia have been associated with some safety concerns, further emphasizing the need for a safe and effective solution.

Growth of the Porcine Vaccine Market in India

Despite the ASF challenge, the overall porcine vaccine market in India is poised for substantial growth. Experts project a significant increase in market size over the next few years, driven by several factors:

• Increasing Disease Prevalence: The rising incidence of various porcine diseases, including CSF, Porcine Reproductive and Respiratory Syndrome (PRRSV), and Porcine Circovirus Associated Disease (PCVAD), necessitates robust vaccination programs.
• Growing Demand for Pork: With an increasing demand for pork and pork products, maintaining healthy and productive pig herds through vaccination becomes economically vital for farmers.
• Government Initiatives: The Indian government's increasing initiatives and funding for the animal husbandry sector, including free CSF vaccination programs under schemes like the Livestock Health Disease Control Programme (LHDCP), are significantly boosting vaccine uptake and awareness.
• Focus on Indigenous Production: The "Make in India" initiative is encouraging local development and manufacturing of veterinary vaccines, reducing reliance on imports and ensuring affordability.

Indian Companies at the Forefront

Indian companies like Indian Immunologicals Ltd (IIL) are actively contributing to the porcine vaccine landscape. IIL was the first company to launch a commercial vaccine against Porcine Cysticercosis (CYSVAX®), a parasitic infection that can cause brain disorders in humans. This vaccine, developed in collaboration with the University of Melbourne, highlights India's role in addressing zoonotic diseases affecting both animal and human health.

The future of pig farming in India is closely tied to the continued advancement and strategic deployment of porcine vaccines. While the hunt for an effective ASF vaccine continues globally, India's proactive efforts in developing indigenous solutions and promoting widespread vaccination will be crucial in safeguarding the health and economic viability of its burgeoning pig industry.
