Presented is an analysis of rabies control of wild animals in different world countries by means of oral ant-rabies vaccines (AV) and their feasibility in RF. Developing actions to immunize wild animals was closely associated with improving the composition of baits and methods to use them. Among modern mostly used but having residual virulence are AV FUCHSORAl and virulence-free AV. These are recombinant AV and vaccines based on deletion mutants – SAG1, SAG2 and ERA G333. There are given recommendation for vaccination against rabies: the area of vaccination should be at least 5000 square km. The best condition for oral vaccination is t +4 to 10 degrees C in the absence of abrupt differences including night frosts. Comparatively, shown was the efficiency of air (aviation) method of spreading vaccine baits against manual method, as the first one is controlled by computer and navigation system GPS allowing accurately document coordinates and frequency of throwing baits. The number of vaccine baits should be at least 25-30 per square km. The minimal duration of vaccination is 6 years and 2 years after the last case of rabies is recorded. For successive development of oral vaccination in RF requires a federal program for rabies control and regional programs based on it, training veterinarian experts in developing programs of oral vaccinations, setting up centralized aviation teams to serve all areas in RF
