Replies on Rabies Titer Gone? Rabies Protection is Not!

Hi Dr. Falconer,
Love your site and am getting a fantastic education as I read through all the articles here.
As I was reading through the above post from last year, I have to admit I am confused by the response you gave to Rebecca (as she has also indicated below) about whether to give the rabies vaccine to her dog. I do understand the legal implications existing in many areas if your dog bites or gets bitten, but suggesting she get a rabies vaccine when it seems clear there are very real health risks (beyond just an itch) in doing so (according to all I have read on this site and elsewhere) seems counter to what you have previously said. From what I have been reading, titers can show antibodies (even for rabies) in an unvaccinated dog.
Were you only speaking to Rebecca's unique case or are you suggesting that a single rabies vaccine is in general, advisable? I had not planned on getting any vaccines for my new pup.
Thanks.

Thank you so much for your detailed reply. I do take this seriously, but have been somewhat conflicted by the differing points, such as on your blog about what "just one rabies vaccine" did. I certainly do not want to have to deal with the tyrannical powers-that-be, and because the exposure factor is dangerous as you have described, then it appears that at least one vaccine will be needed. I have the rabies tautode which I received from you and will use it as instructed to help with any possible problems. Thanks again.
