Symptoms (1)

Product preparation error

Symptom narrative

The error that was made was in relation to the HIB shot. The HIB shot is to be mixed with a saline solution and was mixed in error with sterile water instead. The nurse or aid (not sure of her title or who did it as there were 2 girls in the room doing the vaccines) took the shot out of the room after the tray was brought in, I can only assume that she took the HIB to mix it quickly because it was not completed and/or checked before it entered the room. I have been advised that she should have been supervised and wasn't and this error of her being on her own has caused the wrong mixture of vaccine to be administered to my child. As a mother, I worry about the adverse effects of injecting a toddler with something that was wrongfully mixed and given in error. I have been advised that this mixture makes the vaccine null and void and he will need to go back and get another dose with the correct mixture.

Lab data

No tests or adverse effects have been caught as of today 12/19. But I wanted to report this in case something does happen and to report the error in hopes this does not happen again and other measures are to be taken in the future.

Prior vaccinations

Patient is scheduled to get the vaccine again on 12/26 with correct mixture.
