Baits are usually distributed by aircraft to more efficiently cover large, rural regions. In order to place baits more precisely and to minimize human and pet contact with baits, however, they are distributed by hand in suburban or urban regions.ORV programs have seen success in preventing the westward spread of raccoon variant rabies in the United States and even eradicating rabies in red foxes in Switzerland.The oral vaccine does not contain the whole rabies virus and has been proven safe in over 60 animal species including cats and dogs. The idea of wildlife vaccination was conceived during the 1960s, and modified-live rabies viruses were used for the experimental oral vaccination of carnivores by the 1970s. The potential for human contact with baits is a present concern for ORV programs, but the inactivated rabies vaccine cannot cause rabies, and the recombinant poxvirus vaccine is based on an attenuated poxvirus which is unlikely to cause serious disease in humans anyway. In the USA between 1990 and 2000, over 22 million doses of vaccinia-rabies were distributed, but there were only 160 incidents of people touching a vaccine bait, and only one resulted in a serious infection. The person in this case had been bitten by her dog while removing a bait from its mouth. References

Because of the certain fatality of the virus, receiving the vaccine is always advisable.Vaccines made from nerve tissue are used in a few countries, mainly in Asia and Latin America, but are less effective and have greater side effects. Their use is thus not recommended by the World Health Organization. Types
The human diploid cell rabies vaccine (H.D.C.V.) was started in 1967. Human diploid cell rabies vaccines are inactivated vaccines made using the attenuated Pitman-Moore L503 strain of the virus.In addition to these developments, newer and less expensive purified chicken embryo cell vaccines (CCEEV) and purified Vero cell rabies vaccines are now available and are recommended for use by the WHO. The purified Vero cell rabies vaccine uses the attenuated Wistar strain of the rabies virus, and uses the Vero cell line as its host. CCEEVs can be used in both pre- and post-exposure vaccinations. CCEEVs use inactivated rabies virus grown from either embryonated eggs or in cell cultures and are safe for use in humans and animals.The vaccine was attenuated and prepared in the H.D.C. strain WI-38 which was gifted to Dr. Hilary Koprowski at the Wistar Institute by Dr. Leonard Hayflick, an Associate Member, who developed this normal human diploid cell strain. History
Virtually all infections with rabies resulted in death until two French scientists, Louis Pasteur and Émile Roux, developed the first rabies vaccination in 1885. Nine-year-old Joseph Meister (1876–1940), who had been mauled by a rabid dog, was the first human to receive this vaccine.
