Not so much an adverse event on the patient’s end, luckily, but the pharmacy dispensed an expired vaccine. It was picked up by the patient 12/12/24 and started on 1/18/25. The box states it expired November 2024. The pharmacy then instructed my mother to share her box which was in date with my father, and they would get a replacement in before their 3rd dose was due. Unfortunately, they did not get it in in time forcing both of my parents to need to restart the therapy and neither of them had boxes to do that with as the one given to my dad was expired and the one given to my mother was recommended to be shared between them meaning neither of them could complete the therapy.
