Reporter asks if the practitioner that gave him the second dose injected it incorrectly, and injected it into the bursa sac, would the vaccine come out of the bursa sac and back into his system to be effective or should he get another vaccination. Reporter asks if there is a way of knowing if it came out of the bursa. Reporter stated the vaccine was injected by a pharmacist and if MI has no information for him, why would they.
