He said that the idiot so called pharmacist gave him Pfizer, when he was supposed to be getting a flu shot. RA number for fourth dose of Pfizer vaccine was 59267-1000-03. Initially he said that the LOT could be ending with a zero but then he said it doesn't have the slash like the other zero so he thought it look more like a D.
