No concomitant medication information was provided.  The reporter and her husband (patient) were scheduled to receive the Moderna COVID-19 bivalent vaccine on 25-Oct-2022. They went to a local pharmacy, where they were assured that they will be receiving the Moderna bivalent vaccine. However, on that night she received a call from the pharmacy where they stated that she and her husband along with 200 other patients had received a dose from the pediatric vial instead of the bivalent Moderna vaccine.  According to the reporter, the pharmacy had already called Moderna to get a recommendation and they were told to let the patients know to come in as soon as possible to get their dose of the Moderna bivalent booster vaccine. The reporter however reported that the physician had told her to wait for at least a month to get the next booster dose. The reporter was very confused with these recommendations as Moderna recommended something else to the pharmacy and the physician recommended something else.  No treatment information was provided.
