A 44 year-old female patient received bnt162b2 (BNT162B2), administered in arm left, administration date 10Dec2021 16:30 (Lot number: FD0809, Expiration Date: 19Dec2021) at the age of 44 years as dose 3 (booster), single for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. Vaccination history included: Bnt162b2 (Dose: 1), for COVID-19 immunization; Bnt162b2 (Dose: 2), for COVID-19 immunization. The following information was reported: IMMUNISATION (non-serious) with onset 10Dec2021 16:30, outcome "unknown", described as "Pfizer COVID 19 and this was for her Booster"; PARAESTHESIA (non-serious), BURNING SENSATION (non-serious) all with onset 2021, outcome "unknown" and all described as "Experienced like burning and tingling in her leg and it''s only her right leg; Tingling is pretty bad"; PERIPHERAL SWELLING (non-serious) with onset 2021, outcome "unknown", described as "Very swollen arm like her entire arm and kind of go within into her chest belly area"; DIZZINESS (non-serious) with onset 2021, outcome "unknown", described as "Slight dizziness"; LYMPHADENOPATHY (non-serious) with onset 2021, outcome "unknown", described as "Normal swollen lymph nodes"; RASH (non-serious) with onset 2021, outcome "unknown", described as "Rash". Therapeutic measures were taken as a result of rash.  Additional information: Pharmacist stated, I am a pharmacist calling to report the adverse effect to the vaccine. My name is (Name) (first name further not clarified phonetically hence captured as UNKNOWN in tab). So, the main thing the patient is complaining about is she has experienced like burning and tingling in her leg and it's only her right leg, she had the vaccine in her left arm, I don't know if that's important. But the tingling is pretty bad, and she has also had a very swollen arm like her entire arm and kind of go within into her chest belly area as well and then slight dizziness and then the normal swollen lymph nodes. When confirmed the name of the vaccine as Pfizer COVID 19 Vaccine, Pharmacist stated, Yeah Pfizer COVID 19 and this was for her Booster, she did not have any reaction to the first 2 Pfizer doses. Pharmacist stated, the date was 9Dec (09Dec2021) yes actually let me make sure, she had the vaccine given on 10Dec (10Dec2021). Treatment: Pharmacist stated, she no she took Benadryl for the rash, but that was it (further not clarified hence captured rash as event conservatively). Other medical condition or Concomitant medication: Pharmacist stated, no other condition that I am aware, let me see on her profile. This is all we have ever filled for her, so I am going to say unknown but no (further clarification unknown). Pharmacist stated, she is 44-year-old (further not clarified hence not captured in tab) and vaccine was given to her at 4:30 PM.  No follow-up attempts are possible. No further information is expected.
