Is the vaccine manufacturer's recommendation for frequent "booster"
shots excessive? Immunologically speaking, yes. Studies abound to show
that immunity lasts far longer than one year.

Are these excessive injections harming our animals' health? The evidence
leads me to say, yes, probably, and I'm not going to expose my animals
to the risk when there's no appreciable benefit.

Are vaccines as a whole harmful and should we discontinue their use
altogether? I really, really don't think so. The benefits of having a
vaccinated population are undeniable. But the tendency to consider all
the companion pets in the U.S. as a homogenous group subject to
identical guidelines is outdated and ridiculous; vets need to be making
an individual risk-benefit analysis for every animal that walks in the
door.

OK, off my soapbox. :)
