Symptom narrative

Our clinic was instructed by our Sanofi Representative in early 2012 that we could use Dtap (Daptacel) to reconstitute the ActHIB powder instead of using the provided diluent for ActHIB. These two vaccines were given as combined vaccines to a large number of our patients from March 2012 to April 2025. We have been made aware by our VFC representative and the CDC that these vaccines cannot be combined in this manner and any doses that have been administered as a combined injection should be revaccinated according to the CDC's Catch up Immunization Schedule. This combination of Daptacel and ActHib vaccines was primarily utilized for the 15 month vaccines (dose 4 of Dtap and dose 3 or 4 of Hib). All vaccines given in in this manner are currently being invalidated and patients who are eligible for revaccination are being contacted. Our reports show that approximately 2, 626 patients have been effected by this error. A full report of the patient's names, DOB, date of vaccination and lot numbers can be provided as an uploaded PDF or by email if desired.
