Veterinary Vaccines

Veterinary vaccines are to improve the health and welfare of companion animals, increase production of livestock in a cost-effective manner, and prevent animal-to-human transmission from both domestic animals and wildlife. Several vaccine types can de distinguished among the second-generation veterinary vaccines, depending whether they are live or inactivated, according to the strain of rabies virus used and the characteristics of the cell substrate chosen for viral replication. More recently a third generation of live veterinary rabies vaccine has been developed using recombinant technology. Depending upon the expression system these vaccines are used either parenterally or orally. Oral rabies vaccines are widely used in foxes in Europe and in racoons in the USA.
