chills; tiredness; muscle pain; he also has the snots, so he has a runny nose; had a sore throat; little bit of diarrhea; Insomnia; This is a spontaneous report received from contactable reporter(s) (Consumer or other non HCP) from medical information team. The reporter is the parent.  A 12 year-old male patient received bnt162b2 (BNT162B2), administration date 03Sep2021 (Lot number: FE3592) at the age of 12 years as dose 1, single for covid-19 immunisation. The patient's relevant medical history was not reported. There were no concomitant medications. Past drug history included: Benadryl for counteract an allergic reaction, notes: had even tried to take preventative Benadryl before to counteract an allergic reaction to something in the shot; Flu vaccine, reaction(s): "allergic reaction", notes: They have even tried to take the flu vaccine without the preservative and the only one that they could take was the one that injects up the nose but they have since eliminated that one. That's why they stopped getting the flu vaccine because it got worse year to year and they had even tried to take preventative Benadryl before to counteract an allergic reaction to something in the shot and the same thing would happen. The following information was reported: OROPHARYNGEAL PAIN (non-serious) with onset 06Sep2021, outcome "not recovered", described as "had a sore throat"; CHILLS (non-serious) with onset 07Sep2021, outcome "not recovered", described as "chills"; DIARRHOEA (non-serious) with onset 06Sep2021, outcome "recovered", described as "little bit of diarrhea"; FATIGUE (non-serious) with onset 07Sep2021, outcome "not recovered", described as "tiredness"; MYALGIA (non-serious) with onset 07Sep2021, outcome "not recovered", described as "muscle pain"; INSOMNIA (non-serious) with onset 03Sep2021, outcome "unknown", described as "Insomnia"; RHINORRHOEA (non-serious) with onset 07Sep2021, outcome "unknown", described as "he also has the snots, so he has a runny nose". The event "had a sore throat" was evaluated at the physician office visit. Therapeutic measures were taken as a result of insomnia.  Additional information: The caller was calling to report the side effects and was asking if they should be tested for COVID. She looked online and she saw that this is part of possible COVID. She also needs to add her middle son in there as well because he couldn't sleep until 4 AM. Also, they all had different batches. The caller and her husband had a different batch than what the boys got. Her oldest son didn't get his COVID vaccine until yesterday and he also got his from (Pharmacy Name withheld) but the caller doesn't have his card in front of her at the moment. She took him to school this morning and he called her after his first period and said that he had chills but he has no fever and he doesn't feel warm to her so she hasn't checked his temperature. He has been walking around fine. It is noted that her son hasn't had the flu shot in over 6 years because him and her middle son will swell at the injection site and the spot gets hot to touch. They didn't have those problems with the COVID vaccine. They stayed at the vaccine van for probably about 30 mins to 1 hour and they had no signs of an allergic reaction. She doesn't want them to have anaphylaxis.  No follow-up attempts are possible. No further information is expected.
