Viral Vectors for Veterinary Vaccines

Whatever strategy is adopted for the development of viral vectors for delivery of veterinary vaccines there are several key points to consider: (1) Will the vectored vaccine give a delivery advantage compared to whats already available? (2) Will the vectored vaccine give a manufacturing advantage compared to whats already available? (3) Will the vectored vaccine provide improved safety compared to whats already available? (5) Will the vectored vaccine increase the duration of immunity compared to whats already available? (6) Will the vectored vaccine be more convenient to store compared to whats already available? (7) Is the vectored vaccine compatible with other vaccines? If there is no other alternative available then the answer to these questions is easy. However, if there are alternative vaccines available then the answers to these questions become very important because the answers will determine whether a vectored vaccine is merely a good laboratory idea or a successful vaccine.
