29 Jan Vaccine Basics
Duration of immunity – Duration of immunity is the length of time an animal is protected from a disease.
Antibody titers – A titer is a measurement of antibody to a specific virus (or other antigen). The antibody is in the liquid portion of the blood. With parvo, distemper, and adenovirus titers, the presense of any measurable antibody shows protection in vaccinated doges older than 16 weeks of age. The positive antibody test result is fairly straightforward; it shows you don’t have to revaccinate for these viruses. A negative antibody test result shows you need to vaccinate or revaccinate. Using vaccine antibody testing as a means to asscess vaccine-induced protection is likely to result in preventing the animal from receiving needless and unwise boster vaccinations.
