The intensity of foot-and-mouth disease epizootics and their 
Spread have considerably decreased since the introduction of 
specific active immunization (H. Rerer, 1957; 1958; F. C. Salces, 
1967; . W. Golthals, 1968; J. Borsella, 1970; A. A. Boyko, 1970, 
et ale). 
Owing to immunization, the course of the foot-and-mouth 
disease epizootics has changed and their liquidation has become 
easye 
The analysis of the statistical material available on the 
foot-and-mouth disease epizootics that broke out in Ukraine during 
1965 - 1966 and were caused by the virus of type Ano, allowed us 
to evaluate objectively how the vaccination of cattle influenced 
the course of the epizootic process as a whole as well as efficacy 
of the means used in liquidating an epizootic that began in October- 
December, 1965. 
According to the course assumed by the epizootic in each of 
the regions of the republic and according to the general foot-and- 
mouth disease vaccinations carried out in cattle we have divided 
all the regions into three zones and analyzed them separately. 
The first zone included 10 districts in which the foot-and- 
mouth disease epizootics broke out in October-November, 1965. In 
the initial period of the outbreak the cattle were almost not being 
vaccinated (because of vaccine shortage) and the fight against the 
disease was limited to the use of veterinary-cum-sanitary as well
