Answer: A - West Nile Virus vaccine meets the American Veterinary Medical Association's (AVMA) standard for "core" vaccine requirements. The AVMA defines a core vaccine as those "that protect from diseases that are endemic to a region, those with potential public health significance, required by law, virulent/highly infectious, and/or those posing a risk of severe disease." Core vaccines have clearly demonstrated efficacy and safety, and thus exhibit a high enough level of patient benefit and low enough level of risk to justify their use in the majority of patients.
