Pt was here yesterday afternoon 7/16/25 for a late 15 month WCC with Dr. I administered the patient's scheduled vaccines, her pneumococcal 20 (prevnar 20) and dtap (infanrix) immunizations. However, while preparing the vaccines to be ready for administration, the expiration date on the dtap (infanrix) vaccine was misread and documented as 7-13-2026 and therefore administered. However, after further investigation while gathering other vaccines in the fridge where they were stored, re-evaluation of the date revealed that the expiration of the vaccine was actually 7-13-2025. Therefore the vaccine was 3 days expired. The remaining 1 vaccine dose left in the package was then removed from the vaccine refrigerator and both office manager and Dr. was notified. Attempted to reach parents to inform them of mistake, but no answer. Left a voicemail to call us back to discuss the issue. Further called VFC vaccine management and spoke with someone who reports no further side effects to look for except for the potentially less effective dose due to the expiration date. VFC reports the patient should have another dose of the same vaccine but that is not expired and complete a Vaers form. Spoke with the mother of the patient this morning around 9:50am and explained the situation and offered my sincerest apologies and explained that there is no additional side effects to be watching for and that recommended next steps would be to re-administer a second dose of the same vaccine to ensure effectiveness. Mom was very understanding and appreciative of the notification and that I called and checked to ensure there are no additional side effects or harm conducted to patient. Mom reports she is going to talk to her fiance, the patients father, when he arrives home from work to determine when she can come in for the vaccine as he has the vehicle. vaers form will be completed. Dr. and others are aware of the situation. As of now, there are no known side effects to the patient.
