Symptom narrative

The first vaccination had a mechanical failure in which the vaccine expelled out of the needle junction as the needle may have come loose during administration. This resulted in a subtherapeutic dose. As a result, a second dose was given to the patient to give the patient a full dose. This vaccine was given on the same arm but should have been given on opposite arm to help prevent/lessen side effects. Patient was called on 9/30/25 for follow-up. They described extreme pain from the injection arm that lasted a couple of days after injection. The patient contacted the provider where the provider stated that the injection may have been given too high on the arm. They stated that the pain had subsided to a slight soreness by 9/30/25.
