Clinical narrative: The needle did not retract, she did say there was no fluid left in the syringe."; felt weird; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP) from medical information team for a Pfizer sponsored program (159558). The reporter is the patient.  A 56 year-old female patient received bnt162b2 (BNT162B2), administered in arm left, administration date 16May2021 14:33 (Lot number: EW0185) at the age of 56 years as dose 1, single for covid-19 immunisation. Relevant medical history included: "Diabetic" (unspecified if ongoing), notes: I'm a diabetic so I give myself shots. The patient's concomitant medications were not reported.The following information was reported: INCORRECT DOSE ADMINISTERED (non-serious) with onset 2021, outcome "unknown", described as "The needle did not retract, she did say there was no fluid left in the syringe.""; FEELING ABNORMAL (non-serious) with onset 2021, outcome "unknown", described as "felt weird".  Additional information: Caller stated that she received her first Pfizer shot on Sunday 16MAY2021 at 2:32pm EST. The vaccine administered by the pharmacy tech not the pharmacist. The needle did not retract, she did say there was no fluid left in the syringe. Caller stated, she has gotten lots of shots previously (like the flu shot) and she was a diabetic, so she gives herself shots, She was not watching but it felt weird. She had trouble pushing it down. She said, "oh no, the needle didn't retract." She asked, "will she have my shot?" tech said, "she thinks you got, she don't see any liquid in the syringe." she was shocked, she wants to make sure she has her dosage. The pharmacist said, "that's no big deal, sometimes the needle does not retract because it did not go down. The pharmacist did not see the needle. She said to her, there was a problem, the needle did not retract. The pharmacist said as long as the plunger went down, the retraction part does not matter. She was not 100% sure. She should have stayed there and asked more questions.  She do not see any more liquid. She told her doctor and he said she could get tested in 2 weeks for antibodies. She had no side effects wish she did. Caller asked about the efficacy of 1 dose. Caller asked about having no side effects. Caller stated she was in shock and the pharmacist screamed over to the girl technician what happened and the technician stated the needle did not retract. Caller asked is the Pfizer vaccine the same whether she gets it in a hospital or a drug store? Caller stated this is an easy question that she knows Pfizer can answer. She has a consumer on the line that received the first dose of the vaccine on Sunday 16May2021 and thinks maybe she did not get the full amount because the technician said the needle did not retract but there was no fluid left in the syringe so she thought she got the full dose but did not understand clearly what that meant. The agent is sending the consumer over because of the statement that maybe she did not receive the full dose of the first dose. Also the consumer had no side effects from the vaccine. Person with Pfizer Medical Information also stated that this caller was transferred to her, CEP: 159558. Caller stated she did not see there was no fluid in it that is just what the technician said. Caller stated she has a primary care physician but declined to provide HCP information. Caller stated she did not get the vaccine from her healthcare professional she got it at drug store. Caller stated she thinks the reason she did not get the whole thing is because there must have been a problem with the needle since the technician said oh no and it was very quick so it seemed strange. Caller stated and then the technician said the needle did not retract and the caller knows that can sometimes happen if one does not put down the plunger.
