Abstracts Needforannualrevaccinationof dogsagainst CPVandCDV IT has been questioned whether dogs should be revaccinated annually against canine parvovirus (cPv) and distemper virus(CDV)partly becausethere havebeen reports ofadversereactions,andpartly becausethere has beenresearch suggesting that immu-nity to the two viruses lasts longer than a year. Serum antibodytitres were measured in 122 healthy dogs brought to a clinic forrevaccination. Taking cPv titresof>1:80 and CDV of>1:96 as protective it was found that 33 (27 per cent) of the dogs hadless than the protective level for cPv, and25 of 117 dogs (21 per cent) had less than the protective level for CDV. Theresults sug- gest that the current practice of annual revaccination should bemaintained. MCCAW,D. L., THOMPSON, M., TATE, D., BONDERER, A. &CHEN, Y-J.
