The elimination of rabies from the red fox (Vulpes vulpes) in Western Europe has been achieved by the oral rabies vaccination (ORV) of wildlife with a range of attenuated rabies virus strains. With the exception of the vaccinia rabies glycoprotein recombinant vaccine (VRG), all strains were originally derived from a common ancestor; the Street Alabama Dufferin (SAD) field strain. However, after more...
Despite the extermination of stray animals and the compulsory vaccination of companion animals, rabies has been widely distributed over Estonia for more than 30 years. The red fox and the raccoon dog are the rabies virus reservoirs.Through a PHARE project, successive oral vaccination campaigns, using Rabidog ® SAG2 baits, were implemented in the autumn of 2005 in North Estonia, and in the...
A retrospective cohort study of current rabies antibody titres from adults who received pre-exposure immunisation administered intradermally between 1994 and 2005, examining the decay in titre over time relative to the interval since last dose, and the total dose received. Participants receiving at least 0.6ml total dose intradermally of vaccine over at least two clinic visits and all with three clinic...
There is growing concern in the United States about the excessive use of rabies post exposure prophylaxis (PEP) treatment. In this paper we have estimated the cost effectiveness of rabies PEP treatment under various scenarios of rabies transmission. When the risk of a patient getting rabies is deemed greater than 0.7%, then giving PEP will be cost saving (societal perspective). For lower risks of...
Investigations conducted by public health in Quebec, Canada, following report of human exposure to a bat were reviewed to evaluate the implementation of the recommendation for rabies post-exposure prophylaxis (RPEP) for household bat exposure (without documented direct contact). Of all RPEP recommended, 12% was for direct bat contact with bite, 7% for direct bat contact without known bite and 81%...
The red fox, dog, and raccoon dog are known to play a major role in the global epidemiology of rabies. These three canid species were used to compare the appetency and efficacy of two commercial bait formats, each containing a single dose of vaccinia-rabies glycoprotein (V-RG) vaccine. Square and rectangular RABORAL V-RG baits were fed to individual caged animal, and results were evaluated using three...
Rabies infections in swine have been reported occasionally in recent years in certain geographic locations. Although a protective vaccine consisting of inactivated rabies virus is available for use in swine, searching for a more economically viable formulation for use in developing countries is always a priority. This work describes the testing of a canine adenovirus that expresses a rabies viral...
Immediate passive immune prophylaxis as part of rabies post-exposure prophylaxis (PEP) often cannot be provided due to limited availability of human or equine rabies immunoglobulin (HRIG and ERIG, respectively). We report first clinical data from two phase I studies evaluating a monoclonal antibody cocktail CL184 against rabies.The studies included healthy adult subjects in the USA and India and involved...
Rabies experts from 14 francophone African countries met in Grand Bassam (Côte d’Ivoire), 10–13 March 2008. They presented the situation in their respective countries, acknowledging the lack of rabies awareness among the population, health care workers and health authorities. They recognized that infrastructure for the management of rabies exposure is scarce, modern vaccines are in limited quantity...
Rabies is a deadly zoonotic disease most often transmitted to humans through a dog bite. Human mortality from endemic canine rabies is estimated by WHO to be around 55,000 deaths annually, with over 31,000 deaths in Asia alone, mostly children. Most of these deaths could be prevented through post-exposure prophylaxis (PEP), including immediate wound washing, rabies immunoglobulin administration and...
A sindbis virus replicon-based DNA vaccine encoding rabies virus glycoprotein (G) was developed by subcloning rabies G gene into a sindbis virus replicon-based vaccine vector (pAlpha). The self-amplification of RNA transcripts and translation efficiency of rabies G was analyzed in pAlpha-Rab-G-transfected mammalian cells using RT-PCR, SDS-PAGE and Western blot analysis. The transfected cells also...
A rabies post-exposure prophylaxis study was carried out to examine the efficacy of two commercially available rabies vaccines and the efficacy of a 5- or 3-dose vaccination regime.Healthy, native breed dogs (N=40), seronegative for rabies antibody, were challenged intramuscularly with virulent rabies virus brain suspension (10 4.4 MLD 50 ) by direct inoculation into the masseter muscle...
We tested two post-exposure prophylaxes (PEPs) for rabies in laboratory animals; one was a traditional antirabies vaccine for humans via intramuscular route (IM), and the other was a DNA vaccine administered by intranasal route (IN). In contrast to The World Health Organization’s recommended five-dose PEP, we gave only four doses without hyper-immune antirabies sera, making the PEP more rigorous....
