The reporter is the parent.  A 17-year-old female patient received BNT162b2 (PFIZER COVID-19 VACCINE), as dose 3 (booster), single (Batch/Lot number: unknown) at the age of 17 years for covid-19 immunisation.

Vaccination history included: Covid-19 vaccine (DOSE 1; MANUFACTURER UNKNOWN), for covid-19 immunisation; Covid-19 vaccine (DOSE 2; MANUFACTURER UNKNOWN), for covid-19 immunisation. The following information was reported: LOSS OF CONSCIOUSNESS (medically significant), outcome "unknown", described as "blacking out"; BLINDNESS (medically significant), outcome "unknown", described as "she couldn't see either"; PRESYNCOPE (non-serious), outcome "unknown", described as "it might have been a vasovagal response"; PSYCHIATRIC SYMPTOM (non-serious), DIZZINESS (non-serious), outcome "unknown" and all described as "like very overwhelming feeling like dizziness"; VISUAL IMPAIRMENT (non-serious), outcome "unknown", described as "Some visual disturbances"; PALLOR (non-serious), outcome "unknown", described as "she was really pale/like very pale"; TREMOR (non-serious), outcome "unknown", described as "shaky"; FEELING DRUNK (non-serious), outcome "unknown", described as "looked like she was drunk"; MUSCULAR WEAKNESS (non-serious), GAIT DISTURBANCE (non-serious), outcome "unknown" and all described as "her legs were weak and she couldn't walk"; TACHYCARDIA (non-serious), outcome "unknown". The patient underwent the following laboratory tests and procedures: Blood pressure measurement: normal; Heart rate: tachycardia. Clinical course: Caller was a consumer who reported her daughter (patient) had her booster dose of BNT162b2. Within about 45 minutes she had like very overwhelming feeling like dizziness, she had like some visual disturbances, like very pale and she didn't know. Within 50 minutes she was really pale, shaky. The adult who was with her said she looked like she was drunk, and patient also reported blacking out and her legs were weak and she couldn't walk and she couldn't see either. Caller stated that patient came to her work and she took the blood pressure and it was normal. She didn't eat and drink before the vaccine. Her heart rate was tested and it was tachycardia. She also noted that the patient stated she wasn't nervous about the shot. Caller thought it might have been a vasovagal response. Caller stated that patient was now babysitting, and she was contacted by one of the people there who said "she looked horrible". She wanted to know if this was common, and how closely it would happen to vaccination. It was her 3rd vaccine, so she was very confused what happened and she didn't realize, she just wanted to know if reactions or other than allergic reaction could come that fast (reaction after 45 minutes later).  The information on the batch/lot number for BNT162b2 has been requested and will be submitted if and when received.
