To shed some light on titer testing, the following is from Page 19 the American Animal Hospital Association's 2003 Canine Vaccine Guidelines under the heading "Serological Tests to Monitor Immunity Leerburg | Special Report : it states that "Although the committee does not feel it is necessary to determine titers to these core viruses on an annual basis because of the long minimum DOI [duration of immunity] for these products, titers can be used for your and/or your client's assurance that the animal has immunity. Experience with postvaccination titers for CDV [distemper], CAV [hepatitis], and CPV [parvo] shows that sterile immunity lasts for years...........The primary reason for the test is to ensure that you have a positive test after completing the puppy vaccination series."

2011 American Animal Hospital Association's Canine Vaccine Guidelines https://www.aahanet.org/PublicDocume...Guidelines.pdf p. 17 "Despite the confusion and controversy surrounding antibody testing, these serologic tests are useful for monitoring immunity to CDV, CPV-2, CAV-1, and RV. .....On completion of the puppy core vaccination series with the last dose given at 14-16 wk of age, a dog can be expected to have an antibody titer or positive test result, regardless of the serologic test performed, provided the serum sample is collected > 2 wk after the last dose of vaccine." (CDV=distemper, CPV-2 = parvovirus, CAV-1 hepatitis, RV= rabies)"

From Page 16 of the 2003 AAHA Guidelines it reports that, "The MLV [modified live virus (such as distemper, hepatitis, parvo)] vaccines create an immunity that is similar to immunity after an animal recovers from infection." Further, on Page 17, " When MLV [modified live virus (such as distemper, hepatitis, parvo)] vaccines are used to immunize a dog, memory cells develop and likely persist for the life of the animal."
