Farm animal coronaviruses: the solution is in vaccines

RNA-containing coronaviruses are widespread in nature and can infect a number of vertebrates. Animals are potential sources of human coronaviruses diseases, and interspecies infection by animal coronaviruses has been recorded several times. Such a transmission may have caused the COVID-19 pandemic. The study and control of the spread of farm animals' coronavirus infections is very important, due to the constant close contact between humans and farm animals. Vaccination remains the key to preventing animal diseases and limiting the further spread and transmission of coronavirus infections among poultry and livestock. This review considers coronavirus infections in farm animals, which pose a serious challenge to animal husbandry, and their zoonotic potential and epidemiological features. The review also discusses current vaccines and their limitations, as well as the latest developments and trends in veterinary vaccines aimed at preventing coronavirus infections in poultry and livestock.
