About Vaccine Information Statements. Vaccine Information Statements (VISs) are information sheets produced by the Centers for Disease Control and Prevention (CDC). VISs explain both the benefits and risks of a vaccine to adult vaccine recipients and the parents or legal representatives of. vaccinees who are children and adolescents.
One consistent element of the VIS is the 10th digit, which is required worldwide to encode the model year of the vehicle. Besides the three letters that are not allowed in the VIN itself (I, O and Q), the letters U and Z and the digit 0 are not used for the model year code. The year code is the model year for the vehicle.
