All follow-up information is blended into the case narrative above, with the latest information presented between asterisks (*).  Follow-up information received from other health care professional on 20-Dec-2022: New information included a number of patients vaccinated, confirmation that no patient had a relevant medical history and was not taking any concomitant medication, confirmation that no patient experienced any adverse event due to Jynneos, vaccination details for all patients and information that patients' personal details can't be disclosed.; Reporter's Comments: On an unspecified date, Jynneos vaccine was thawed for more than 60 days, which is considered as product storage error. Five patients of unknown demographics in total received the affected vaccine at a dose of 0.1 mL, intradermally for monkeypox and smallpox prophylaxis. Reportedly, three out of five patients also received second dose more than 28 days after the first dose, which is considered as inappropriate schedule of vaccine administered. No associated adverse events were reported. Product administration error, product storage error, intradermal injection and inappropriate schedule of vaccine administered are listed per company convention. The patients had no relevant medical history and were not taking any concomitant medication. Product administration error, product storage error, intradermal injection and inappropriate schedule of vaccine administered are not related to Jynneos, but to a human factor. The case is non-serious.; Sender's Comments: On an unspecified date, Jynneos vaccine was thawed for more than 60 days, which is considered as product storage error.
