Patient came in to clinic to get updated vaccines. He was due for Dtap and polio and is 5 years old. He was unintentionally given more vaccines than necessary at the time. He was given vaxelis which contains DTaP, IPV, HIB, and Hep B; it is intended for use from 6 weeks to 4 years of age. There was also a separate IPOL (polio/IPV) vaccine given. Reviewing this patients vaccine record, it appears he should have gotten either Kinrix (DTaP & IPV) which is for 4 years to 6 years of age or Infanrix (DTaP) and IPOL (polio/IPV). The MA in charge of the patient and asked (redacted) and (redacted) to perform the vaccines which they did. In the rush and because they just stepped in to help they accidentally gave him the wrong vaccine. The next day patients mom called asking why his vaccines weren’t showing up as updated in his chart. As this was being looked into we realized the mistake of the incorrect vaccine. We contacted the state to see what needed to happen and what this all meant. Through this we discovered that all of his vaccines including the ones he was getting updated were still valid but just needed to inform the parents and check for adverse reactions to vaccines as we generally would with any vaccine. Mother was contacted and informed. Mother stated that both of patients arms were red, he had been vomiting and had some fever but confirmed that he was having no problems with breathing. We told her that we would recommend she brought her son in to a provider to be evaluated for his reaction.
