The patient's medical history included vitiligo from an unknown date (she was diagnosed with Vitiligo on her left arm only at the age of 2. Her Vitiligo hasn't gotten any worse since she was 2 years old). The patient's concomitant medications were not reported. The patient previously received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Batch/Lot number: unknown, Expiration date: unknown) intramuscular, administered in left arm on an unspecified date in Apr2021 (age at vaccination was 18 years) as dose 1, single for COVID-19 immunization and the patient had no symptoms, not even a sore arm, with her first COVID-19 Vaccine dose. No additional vaccines were administered on same date of the Pfizer suspect. The facility where the most recent COVID-19 vaccine was administered was Hospital. The vaccine was not administered at Military facility. The patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. The patient was fine before she took the second COVID-19 Vaccine dose that day. The patient told the reporter that she was fine yesterday (06May2021) and today (07May2021), she woke up feeling miserable. On 07May2021, the patient had half of the symptoms of the COVID-19 Vaccine listed. The reporters biggest concern out of the symptoms the patient was experiencing was a fever and was reported as worsened. The reporter asked what kind of fever (high temperature) should be expected as a side effect of the COVID-19 Vaccine. The patient had a fever since that morning. The patient took Tylenol and her temperature kept getting higher. The patient had a 101.3 degree low grade fever. The patient was complaining about having chills and then being very hot. The reporter thought with the patient experiencing chills, her fever wouldn't be up. The patient also was feeling hot and then feeling cold, had chills, nausea, headache and tiredness. The patient said she felt like she was hit by a car. The patient was very nauseated too, so he told her to take the Tylenol (generic Tylenol) with water only. The patient hated to throw-up. She didn't take any nausea treatment, though her mother was going to bring her some Gatorade and ginger ale. She was afraid to eat anything because of her nausea. The patient was recently prescribed a new medication for acne, but the patient hadn't started the new medication yet because she had to have 2 negative pregnancy tests before she could start the medication. The patient only had 1 out of the 2 pregnancy tests, so far. That morning the patient took Tylenol, clarified as generic Tylenol 500mg tablet. The patient took 1-1/2 generic Tylenol 500mg tablets (750mg total). The reporter did not have the generic Tylenol 500mg tablet. The patient took the Tylenol (generic Tylenol 750mg) that morning and then the reporter told her to take more Tylenol (generic Tylenol) when he spoke with her about an hour ago. The patient's symptoms weren't bad, but her symptoms were definitely from the COVID-19 Vaccine. The patient was told not to take Motrin or Ibuprofen for 14 days after the COVID-19 Vaccine. The reporter asked if there was a cut off on what was an acceptable fever to have after getting the COVID-19 Vaccine. The adverse events did not require a visit to Emergency Room or Physician Office. The outcome of the event his daughter felt like she was hit by a car was unknown. The outcome of the other events was not resolved.  No follow-up attempts are needed; information about lot/batch number cannot be obtained.
