Abstract
Methods to measure the duration of adequate immune memory for animal vaccines involving a retrospective analysis utilizing veterinary vaccine administration histories and clinical histories, and markers of immunity of animals in the field to derive a vaccine's duration of adequate immune memory.
Claims10
A method of determining a duration of adequate immune memory induced by a vaccine for a disease in an animal, the method comprising:
- (a) selecting a plurality of study animals from one or more clinics, where each animal has been vaccinated with the vaccine and where a time since a last vaccination date is at least about one year and the animal has been living in a field environment for at least about one year after the last vaccination date and each animal has a vaccine administration record;
- (b) assigning each animal an indicator of immune memory, such that each animal that does not have a marker of immunity is assigned a first indicator and each animal that has the marker of immunity is assigned a second indicator;
- and
- (c) determining the duration of adequate immune memory from:
- (i) the first indicator and the second indicator;
- and (ii) the vaccine administration record.
