The only reason for the series of vaccinations for the young animals
is to "catch" them when the maternal antibodies have worn off and
the vaccine will be effective. Because each animal is different and
maternal antibodies don't wear off at the same time, they do the series
with the intent that they all will be vaccinated with a minimal amount
of time without maternal antibodies. You could give ONE vaccine after
about 16 weeks or so and not have to do the series. If the animal is an
adult then one vaccine is fine even if they have NEVER been vaccinated
before. You don't boost immunity, it is there or it isn't. I believe
the question was regarding a ferret that was not a kit? Your vet is
wrong in advising a second vaccine 30 days later and is putting your
ferrets health at risk. Ferrets are already over vaccinated with the
yearly "booster" protocol being the norm, but recommending a series for
a ferret that maternal antibodies have most definitely worn off is very
negligent. Vets and people have to realize that vaccines are not water
and stop giving them like they are. If your vet is not going to educate
him or herself, then it is up to the owner to and to say no to that
practice of a series with adults that has no scientific basis and is
health endangering.
