Think I would do a course of the homeopathic nosode, give it time to take (maybe a fortnight, but I don't really know) then get another titre done, and boost if really still necessary. However, really needs a homeopathic vet to advise, not me! I know it's more expense, but it's a cautious option given his history.
I was told once (again, can't remember where or when) that the human measles vaccine give immunity to distemper, but you're unlikely to find a vet who would gamble with that!!!!
