Vaccine information statements (VIS) that explain the benefits and risks of tetanus/diphtheria (Td) and Haemophilus Influenzae Type b (Hib) vaccines have been updated by the Centers for Disease Control and Prevention (CDC). Because both statements include changes in the adverse events section (“problems that can happen after any vaccine”), health officials advised healthcare providers to begin using them immediately. The Td VIS replaces a Td/Tdap VIS which was temporarily in use for Td alone. The new Hib edition allows the CDC to retire what it calls the “elder statesman” of VIS. Federal law requires healthcare staff to provide an information statement to a patient, parent or legal representative before each dose of certain vaccinations. The CDC said provider guidelines for both vaccines will be available soon.
