They had a box of Menveo vaccine and when, he/she had a clinical staff nurse that went to administered the last dose and noticed there were 2 vials of the concentrate, if they would and only one bottle of the diluent in there. So, it appeared that one of our patients they were not sure which of the four others had only the diluent and not the full dosing of the Menveo, which led to inappropriate preparation of medication and inappropriate dose of vaccine administered.
