temperature was 104/fever; severe shaking; Contracted Covid after booster; Contracted Covid after booster; took 2 months to "get my strength back in my muscles and my throat actually closed up"; took 2 months to "get my strength back in my muscles and my throat actually closed up"; swelled up; rash; chills; hives; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP) from medical information team. The reporter is the patient.  A female patient received bnt162b2, bnt162b2 omi ba.4-5 (BNT162B2, BNT162B2 OMI BA.4-5), as dose 3 (booster), single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. Vaccination history included: Covid-19 vaccine (Dose 1; Manufacturer Unknown), for COVID-19 Immuniztion; Covid-19 vaccine (Dose 2; Manufacturer Unknown), for COVID-19 Immuniztion. The following information was reported: DRUG INEFFECTIVE (medically significant), COVID-19 (medically significant), outcome "unknown" and all described as "Contracted Covid after booster"; PYREXIA (hospitalization), outcome "unknown", described as "temperature was 104/fever"; TREMOR (non-serious), outcome "unknown", described as "severe shaking"; URTICARIA (non-serious), outcome "recovered", described as "hives"; MUSCULAR WEAKNESS (non-serious), outcome "recovered", THROAT TIGHTNESS (non-serious), outcome "unknown" and all described as "took 2 months to "get my strength back in my muscles and my throat actually closed up""; SWELLING (non-serious), outcome "unknown", described as "swelled up"; RASH (non-serious), outcome "unknown"; CHILLS (non-serious), outcome "unknown". The event "contracted covid after booster" required emergency room visit. Product is Pfizer BioNTech Covid-19 vaccine, not most recent release of product, the prior booster doses for adults. This was booster, third covid vaccine. Caller (patient) stated she had been putting off getting the most recent vaccine because of what she had experienced as well as the death of family members from the Delta variant of Covid 19. Caller stated she "Got really really sick" the last time she took the vaccine.  She still got Covid and then got really, really sick with Covid as well and was almost hospitalized.  She had two boosters and got extremely sick both times. She stated her reaction to the booster was "like I had actually been injected with a live virus." Her temperature was 104, she was packed in ice, had severe shaking and "everything else." She experienced hives, was sick for a week, took 2 months to "get my strength back in my muscles and my throat actually closed up" which is why she ended up in the hospital with a fever.  Her reaction to the vaccine was almost identical to her reaction when she contracted Covid 19. Her reaction to the virus and the vaccine was almost the same. Caller stated she didn't hear a fever of 104 as a side effect. When she got the vaccine and had to go to the hospital it cost her $# out of pocket as well as another $# out of pocket when she got sick with Covid and was hospitalized. This was a big deal for her financially. Nothing is covered anymore. She can't afford to get sick or have a reaction to the vaccine because she doesn't have another $# for the hospitalization. Caller got 2 boosters, got extremely sick both times. Her reaction to vaccine was almost identical to what happened when she was sick with Covid. Clarified, that she actually contracted Covid after that, had similar reaction. Therapeutic measures were taken as a result of pyrexia.  The information on the batch/lot number for bnt162b2, bnt162b2 omi ba.4-5 has been requested and will be submitted if and when received.
