Figure 1: Vaccination of animals and the course 
of the foot-and-mouth disease epizootics 
in the first zone. 
12 mumber of affected animals; 
2e number of animals becoming immune as a 
result of their pulling over, vaccination 
and revaccination; 
3e number of vaccinated and revaccinated animals; 
4, the actual period of the epizootics being 
stopped; 
5e theoretical calculations of the periods at 
which the epizootics came to an end. 
Key: 1.Number of animals, %; 2.Months. 
In the third zone (Figure 3) the animals were being already 
immunized with the foot-and-mouth disease vaccine before the 
outbreak and hence 94.2% of the cattle were not susceptible to 
foot-and-mouth diseasee These districts contained only 7.9% of 
all the affected foci in Ukraine with 4.5% of animals being sick. 
The epizootics stopped five months after they began. The theore- 
tical calculations and the periods at which the epizootics 
actually stopped coincided. 
Thus, in the liquidation of the foot-and-mouth disease 
epizootics in Ukraine caused by the virus of type A5>5 along with 
the strictly implemented organizational-cum-administrative and 
veterinary-cum-sanitary measures very important was the use of 
prophylactic vaccination, which in the beginning put a stop to 
the spread of epizootics and then made its liquidation easy.
