VISI proposed standard abbreviations for vaccine types and manufacturers and distributors. One purpose is to minimize misinterpretation of a variety of ad hoc notations used in medical records, which may lead to erroneous conclusions as to the actual vaccine type and brand administered to a patient. Another advantage of standard abbreviations is when space limitations on very small peel-off stickers prevent printing the full generic names of very large combination vaccines, and the full names of manufacturers or distributors.
