African Swine Fever in India:India appears close to achieving its first substantial success against African Swine Fever (ASF) as its vaccine has reached the second testing phase at a Chhattisgarh farm. The state needs to implement an efficient disease control system because new outbreaks have emerged during this vital period.
Rising Threat of African Swine Fever in India
African Swine Fever exists as a pig viral disease that spreads easily between animals and leads to almost complete death in serious instances. The virus infects pigs but not humans which creates severe financial damage for both farmers and the pork industry.
Authorities in Durg district of Chhattisgarh implemented strict pig containment procedures after an outbreak occurred. The authorities established infected and surveillance zones to prevent virus spread after laboratory tests confirmed the disease’s presence.
“The infection spreads through the blood, faeces, urine, and saliva of infected pigs. The symptoms appear 4–19 days after infection. In this disease, pigs suffer from high fever, loss of appetite, weakness and lethargy, breathing difficulty and develop red and blue spots on the skin,” senior veterinarian Dr Chandra Kumar Mishra explained.
The ongoing occurrence of outbreaks demonstrates that researchers have not yet developed an effective vaccine which remains one of the main obstacles to controlling ASF in different countries.

Vaccine Development Enters Crucial Phase II Trials
The latest reports indicate that an indigenous ASF vaccine candidate is now undergoing Phase II trials at a farm in Chhattisgarh. This phase evaluates three essential components which include:
- The evaluation of safety through testing on multiple animal subjects
- The assessment of how well the body defends itself against health threats
- The examination of protective capabilities under actual agricultural conditions
“African swine fever is a deadly viral disease that affects domestic and wild pigs, causing up to 100 percent mortality rates. The vaccine for this disease has been developed at ICMR’s lab in Bhopal and the trials are being done at the government-run Ambikapur pig farm. If this vaccine is successful then it will immensely benefit the pig breeders,” Dr Chandra Kumar Mishra said.
The development of an ASF vaccine faces worldwide challenges because the virus possesses intricate structural elements which enable it to avoid immune system detection.
The research shows that previous vaccine development efforts encountered failure because they could not create sufficient immune responses or they raised safety issues.
Race for ASF Vaccine
ASF has affected multiple countries across Asia, Europe, and Africa. A total of 11 countries have started to develop vaccine candidates even though Vietnam has already made its public announcement. The scientific community has yet to establish any vaccine that meets all safety and efficacy requirements for widespread application.
India’s progress in this area could position it among global leaders in veterinary vaccine innovation.
Experts caution that even successful trials must prove consistent protection across diverse conditions.
