All follow-up information is blended into the case narrative above, with the latest information presented between asterisks (*).  Follow-up received from the other healthcare professional on 27-Jan-2023 included the number of patients to which affected vaccines of Jynneos were administered.  Additional information received from the other healthcare professional on 03-Feb-2023 included confirmation of number of patients, additional patient's details, batch number, dates (which caused additional non-event of 'inappropriate schedule of vaccine administered' and 'incomplete course of vaccination' to be added), anatomical location, and route of every administered dose.  Additional information received from the other healthcare professional on 06-Feb-2023 included confirmation that no patient experienced any adverse event.; Reporter's Comments: In this case Jynneos vaccine was refrigerated, but it was placed in the freezer (-20 degrees Celsius), then thawed again and then 194 patients were vaccinated at an unknown doses or sites of administration, intradermally, some subcutaneous, for an unknown indication, which is considered as product storage error and product administration error. Some of the patients, from the 61 patients who received both the first and second doses of Jynneos received the second dose of Jynneos more than four weeks apart from the first dose, which is considered as inappropriate schedule of vaccine administered. There is no information regarding administration of second Jynneos dose for several patients who received the first dose during October, November or December 2022, which is considered as incomplete course of vaccination. Product storage error, product administration error, inappropriate schedule of vaccine administered, incomplete course of vaccination and intradermal injection are all considered listed per company conventions. No associated adverse events were reported. The patients' medical history and concomitant medication details were not provided. Product storage error, product administration error, inappropriate schedule of vaccine administered, incomplete course of vaccination and intradermal injection are all assessed as not related to suspect product but to human factor. The case is non-serious.; Sender's Comments: In this case Jynneos vaccine was refrigerated, but it was placed in the freezer (-20 degrees Celsius), then thawed again and then 194 patients were vaccinated at an unknown doses or sites of administration, intradermally, some subcutaneous, for an unknown indication, which is considered as product storage error and product administration error.
