ADV has now been 100% diagnosed in Holland, Dutch ferrets are vaccinated with multi vaccine, As research is being done into which ferrets now have ADV, It is clear that all infected ferrets are the ferrets that have been in close contact with the ferrets that came from New Zeeland and brought this virus to Holland. I'm afraid that giving your ferret the parvo vaccine will not stop them getting ADV if they come into contact with an ADV positive ferret, Most of the ferrets tested and found positive have been vaccinated every year with a multi vaccine.
