vanguard plus cpv is licensed for vaccination of healthy dogs 6 weeks of age or older as an aid in the prevention of canine parvoviral enteritis caused by canine parvovirus (cpv). in addition, cross-protection against cpv type 2c has been demonstrated.
vanguard plus cpv is a high-titer, modified-live canine parvovirus (cpv) strain attenuated by low passage on an established canine cell line. the combination of high titer and low passage gives vanguard plus cpv the immunogenic properties capable of stimulating active immunity in the presence of maternal antibodies. some puppies may have higher levels of maternal antibodies than those evaluated in our pivotal efficacy study.
