Vaccines help dogs fight rabies in short-term

Anti-rabies vaccines used in the first phase of the mass vaccination drive in Bali have proven effective, with the immunized dogs showing a good response to fighting infection.
The Denpasar Veterinary Main Office (BBVet), however, advised that the local administrations provide vaccines with a longer protection period.
The current vaccine offers short-term protection period, which means a mass vaccination drive must be organized every four months.
Additionally, it is reportedly difficult to administer the first shot to the street dog population, let alone to give the second or the third shot.
BBVet head Enuh Rahardjo said it was necessary to use a vaccine with a longer protection period considering the low number of dogs receiving booster (second shot) vaccines, which was only around 25 percent.
"It is difficult to give the dogs booster vaccines since 70 percent were hard to catch. Therefore, a longer-lasting vaccine is needed to prevent another outbreak."
BBVet is a government body tasked with monitoring, preventing and mitigating contagious diseases among animals and live stocks.
The Denpasar office is responsible for Bali, West Nusa Tenggara and East Nusa Tenggara.
The agency reported the vaccine had stimulated the development of antibodies in more than 70 percent of the dogs, with the concentration of the antibody reaching a minimum of 0.5 International Units.
The concentration is considered effective in protecting dogs from the lethal virus, although it was still lower than the level of immunity developed by vaccines used in other countries.
The agency, however, found two vaccinated dogs contracting rabies, saying it was possibly because the dogs had been given vaccines with a short-term effect of six months.
BBVet also called on the Animal and Husbandry Agency to be more organized in applying collars to dogs after they had received vaccines.
The canine population in Bali receives two types of vaccines with different level of immunity, each of which is represented by differently colored collars.
As of November last year, there were 63 cases of rabies in animals, 62 of which were found in dogs and another one in cow. Out of the dog cases, 61 occurred in stray dogs.
Most of the dog-biting cases occurred in Ungasan village in the south part of Badung regency, which accounted for 24 percent of the total cases.
The BBVet data showed the first case of rabies in a human was found on June 10, 2008, in Ungasan, where a villager died 220 days after being bitten on the leg by a stray dog.
Considering the incubation period of rabies virus in a dog's body of about one or two months, the agency estimated the first infected dog entered the Semenanjung Bukit in Badung in April 2008.
"We have yet to find out how the dog entered the area," Enuh said.
"Java experienced a rabies outbreak for 10 years. The same thing could occur in Bali, and would be even worse due to the island's uncontrolled dog population."
