• Administering Vaccines
  • Vaccine Administration Errors

My medical assistant inadvertently administered a 0.5 mL dose of the RZV (Shingrix) diluent only. The dose did not contain any antigen. When can we administer a properly reconstituted dose?

The CDC zoster subject matter experts recommend that in this situation you should wait 4 weeks before giving a repeat dose.
