Here's a link to the Report of the American Animal Hospital Association (AAHA) Canine Vaccine Task Force: 2003 Canine Vaccine Guidelines, Recommendations, and Supporting Literature. Have you seen this? We now know that booster injections are of no value in dogs already immune, and immunity from distemper infection and vaccination lasts for a minimum of 7 years based on challenge studies and up to 15 years (a lifetime) based on antibody titer [Table 2].
Dogs with a CDV antibody titer, no matter how low when challenged, may become infected if antibody levels are below titers which provide sterilizing immunity (i.e., resistance to infec-tion), but they will have protection from clinical disease mediated by an anamnestic humoral and CMI response.
The economics of the 1960s remains unchanged today. Piercy’s statement that “it would be less expensive to vaccinate than to have the animal bled and an antibody titer performed” remains, for the most part, relevant to today’s practice economics. However, the ethical issue that our profession struggles with today is whether eco-nomics justifies giving an animal a drug (vaccines are biologic drugs) that is not necessarily required. As a minimum, we should allow pet owners to make this choice rather than make it for them.
