C. Biologicals, biologics or biological products are all terms that cover materials used for vaccination. Living viruses are used to stimulate antibody production against a specific virus without the animal contracting the disease. Another example is canine distemper vaccine. This type of vaccine confers an effective and long lasting immunity. These agents have a relatively lower power to confer immunity and must be re-administered at least once every 12 months.
Toxoids provide long-lasting protection against problems such as tetanus and enterotoxemia.
