The vaccine is known as Rabisin (Mérial), which is a cell based rabies vaccine only used countrywide. Vaccinations are often administered when owners take in their dogs for check-ups and visits at the vet.Oral rabies vaccines (see below for details) have been trialled on feral/stray dogs in some areas with high rabies incidence, as it could potentially be more efficient than catching and injecting them. However these have not been deployed for dogs at large scale yet. Wild animals
Wildlife species, primarily bats, raccoons, skunks, and foxes, act as reservoir species for different variants of the rabies virus. This results in the general occurrence of rabies as well as outbreaks in animal populations. Approximately 90% of all reported rabies cases in the US are from wildlife. Oral rabies vaccine
Oral rabies vaccines in pellet form are intended to be given to wild animals to produce a herd immunity effect. The development of safe and effective rabies virus vaccines applied in attractive baits resulted in the first field trials in Switzerland in 1978 to immunize red foxes.There are currently two different types of oral wildlife rabies vaccine in use:

Modified live virus: Attenuated vaccine strains of rabies virus such as SAG2 and SAD B19 
Recombinant vaccinia virus expressing rabies glycoprotein: This is a strain of the vaccinia virus (originally a smallpox vaccine) that has been engineed to encode the gene for the rabies glycoprotein.
Nonetheless, it has been used successfully in many cases of central nervous system infection—including meningitis—caused by susceptible bacteria, and has also been suggested as a reasonable choice for this indication when treatment options are limited or when other antibiotics have failed. The guidelines of the Infectious Diseases Society of America recommend linezolid as the first-line drug of choice for VRE meningitis, and as an alternative to vancomycin for MRSA meningitis. Linezolid appears superior to vancomycin in treating community-acquired MRSA infections of the central nervous system, although very few cases of such infections have been published (as of 2009). Catheter-related infections
In March 2007, the FDA reported the results of a randomized, open-label, phase III clinical trial comparing linezolid to vancomycin in the treatment of catheter-related bloodstream infections. Patients treated with vancomycin could be switched to oxacillin or dicloxacillin if the bacteria that caused their infection was found to be susceptible, and patients in both groups (linezolid and vancomycin) could receive specific treatment against Gram-negative bacteria if necessary. The study itself was published in January 2009.Linezolid was associated with significantly greater mortality than the comparator antibiotics. When data from all participants were pooled, the study found that 21.5% of those given linezolid died, compared to 16% of those not receiving it. The difference was found to be due to the inferiority of linezolid in the treatment of Gram-negative infections alone or mixed Gram-negative/Gram-positive infections. In participants whose infection was due to Gram-positive bacteria alone, linezolid was as safe and effective as vancomycin.
