QUESTION: HOW TO PREVENT CDV?

ANSWER: With the potential increasing virulence of emerging strains and the wide host range of canine distemper virus (cdv), widespread vaccination of domestic dogs is essential.

Successful immunization of pups with canine distemper modified-live virus (MLV) vaccines depends on the lack of interference by maternal antibody. To overcome this barrier, pups are vaccinated with MLV vaccine when 6 wk old and at 3- to 4-wk intervals until 12-16 weeks old. Efficacy of CDV vaccines approaches 99% and dogs develop protective immunity within a few days after vaccination.
