On the same day, the patient recovered from the events 'oropharyngeal pain' and 'pruritus' (after applying cortisone cream).  At the time of this report, the outcome of the events 'acne', 'injection site erythema', 'injection site mass', 'nasal congestion' and 'influenza like illness' was reported as not resolved/ongoing.  The reporter assessed all the events as non-serious and possibly related to Jynneos.  Additional information received from Bavarian Nordic on 01-Sep-2022 included local case ID.; Reporter's Comments: A 72-year-old male patient was vaccinated with the first dose of Jynneos administered intradermally in the left forearm, which is considered as inappropriate route of vaccination, at a dose of 0.1 mL, which is considered as underdose, for monkeypox prophylaxis (exposure to someone with monkeypox). Reportedly, on the day 0 after the vaccination, the patient experienced non-serious events of acne, injection site mass and injection site erythema. On the day 1 after the vaccination, the patient experienced non-serious events of oropharyngeal pain, nasal congestion, and influenza like illness. Reportedly, on the day 3 after the vaccination, the patient experienced a non-serious event of pruritus. Injection site erythema is listed for Jynneos according to the insert, whilst underdose and incorrect route of product administration are considered as listed per company convention. Influenza like illness, injection site mass, oropharyngeal pain, nasal congestion, and pruritus are listed per insert and unlisted per insert. Acne is unlisted both per insert. The patient's medical history and concomitant medication details were not provided. The patient recovered from the events of oropharyngeal pain and pruritus, whilst the outcome for the rest of the events was reported as not resolved. Considering plausible temporal relationship and since the contributory role of the suspect vaccine cannot be excluded, all the events have been considered as related to Jynneos.

This case is considered as non-serious.; Sender's Comments: A 72-year-old male patient was vaccinated with the first dose of Jynneos administered intradermally in the left forearm, which is considered as inappropriate route of vaccination, at a dose of 0.1 mL, which is considered as underdose, for monkeypox prophylaxis (exposure to someone with monkeypox).
