SYDNEY (Reuters) -A vaccine to protect Australia's koalas against chlamydia has been approved for the first time, a move that scientists believe could stop the spread of the deadly disease that has ravaged populations of the beloved endangered marsupial.
The single-dose vaccine is now ready to be used nationally at wildlife hospitals, clinics and in the field.
