Additional Information
Vaccine Information Statements (VIS) are made by the staff of the Centers for Disease Control and Prevention (CDC). Each VIS gives information to properly inform the adult receiving the vaccine or, in the case of a minor, the child’s parent or legal representative about the risks and benefits of each vaccine. Before a doctor vaccinates a child or an adult, the provider is required by the National Childhood Vaccine Injury Act to give a copy of the VIS. You can also get foreign language versions.
