Anthrax poses a serious health issue for unvaccinated livestock, is a threat to humans through interaction with contaminated livestock and animal products and is endemic in many areas throughout the world, including the Transcaucasian Region. Despite several control and eradication efforts that have been implemented by the government of the Republic of Armenia (RA), sporadic cases of anthrax are still reported.

The transmission of lumpy skin disease (LSD) occurs through ticks, mosquitoes, and flies. The most effective way to combat LSD is to conduct large-scale vaccination, covering the entire cattle population with safe and effective vaccines, while introducing restrictions on the movement of livestock. The first and only LSD cases that occurred in Armenia happened in 2015,and they were controlled with the use of a once yearly heterologous sheep pox vaccine for cattle in high-risk areas.

Article Synopsis
  • Foot-and-mouth disease (FMD) is a serious viral infection affecting livestock, and vaccination is critical for controlling its spread in Armenia, especially since it borders countries where FMD is common.
  • A study in three regions of Armenia assessed the immune response of cattle and sheep to a polyvalent vaccine over time, finding that over 90% of vaccinated animals had protective immunity shortly after vaccination, but this declined significantly by 90 days.
  • The findings indicate that while initial vaccination offers strong protection, re-vaccination is necessary to maintain adequate immunity levels in both cattle and sheep, highlighting the need for ongoing vaccination strategies to control FMD in Armenia.
