CSIRO scientists have shown that a new experimental vaccine helps to protect horses against the deadly Hendra virus.
Dr Deborah Middleton from CSIRO’s Australian Animal Health Laboratory (AAHL) has announced the successful progress to develop the vaccine, at the recent Australian Veterinary Association conference.
“Our trials so far have shown that the vaccine prevents the infection of horses with Hendra virus,” Dr Middleton said.
Stopping the disease in horses could also help protect people from the disease.
“A horse vaccine is crucial to breaking the cycle of Hendra virus transmission from flying foxes to horses and then to people, as it prevents both the horse developing the disease and passing it on.”
The Hendra virus first appeared in 1994 and five of the 14 known outbreaks have spread to people. The virus has killed four of the seven people infected.
Depending on further development, field trials and registration of the vaccine may be available as early as 2012.
Dr Barry Smyth, President of the Australian Veterinary Association, said that the news on the vaccine will be welcomed by both vets and horse owners.
“It’s important that veterinarians and horse owners continue with precautions that reduce the risk of spreading the virus and that they report suspected cases immediately,” Dr Smyth said.
Recent work on evaluating the vaccine was jointly funded by the CSIRO, the Australian Government Department of Agriculture, Fisheries and Forestry and the Queensland Government Department of Employment, Economic Development and Innovation.
