I remember this. A lot of my friends horses got sick from it and some passed away from the Hendra jabs. The virus was originally detected in a group of racehorses owned by a trainer called Vic Rail who trained a champion called Vo Rogue. It was at his Hendra property in Queensland hence the name Hendra. Horses pick it up by grazing in areas where there are fruit bats that defecate and urinate on pastures.

When this lady posted about this originally on that group ,FB removed the post within a few hours.
