On farms that are unsafe or potentially unsafe with respect to avian pseudoplague it is advisable to use methods that make it possible to vaccinate a large poultry population with a minimum expenditure of effort and means in a relatively short period of time. One of these methods is that of aerosol immunization. The objective of this research was to study the immunogenicity and reactogenicity of Strain N pseudoplague virus in chickens of various age groups vaccinated with aerosols of liquid virus vaccine and simultaneously to establish the degree of influence of transovarian passive immunity on the formation of postvaccinal immunity and to determine the extent of inactivation of Strain N virus vaccine when it is dispersed with compressed air.
