A 15-year-old male patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Batch/Lot number was not reported) via an unspecified route of administration, administered in left arm on 21Jul2021 08:56 (at the age of 15 years old) as dose 1, single for COVID-19 immunization. The patient has no medical history and there were no concomitant medications. No additional vaccine was administered on the same date as the Pfizer suspect. The patient previously took HPV shot and Flu shot for Immunization. No one in his family has epilepsy or has had a reaction to the vaccine. Yesterday, on 21Jul2021, he went to the high school where they were giving out the vaccine and he was given the injection. Then, everything started to go black. His mother was next to him and apparently he passed out and it looked like he started seizing. He woke back up, passed out again, woke up and EMS was called. He added that everything started to go black, like when you stand up and you have an iron deficiency and everything gets dark and start to pass out. Within not even like 3 to 5 minutes, he started feeling weird and disoriented. He started reading about all of the side effects and he could not see the paper anymore. He could not see anything clearly anymore. Everything was getting hazy and got darker. Apparently, he passed out and it looked like he started seizing. His Mom said that she saw his head and was bobbing at first, then she called his name twice and he was unresponsive. She started shaking him and he felt himself fall asleep. She woke him up and his arm was curled up under his chest and he was sliding off the chair. His Mom said that it was internal, said that it all happened within a span of 10 minutes. He was out for about 10 seconds and he woke up and told everyone he was fine. He stood up and sat back down and everything was hazy, then he passed out. EMS was then called. States he did not go to the hospital, that would have been a costly trip. They took his blood pressure and that was it. Everything kind of stopped, but for the rest of the day, even today, like this morning, he felt disoriented. It was like everything he was looking at is coming back to him. He still remembered everything and school work, he just felt weird. He does not feel it anymore but, his left arm, where he was injected, hurts; but commented that is normal. When she gave it, it felt it coursing through his body. His body felt weird and he felt disoriented. In the morning, he woke up and it hurt, sore. It has been hurting all day but that is normal. It is like a flu shot, or any shot. He stated that he did not receive a vaccine card or any information with dates NDC, LOT, EXP. The only thing he has is a sticky note that said he could leave at 09:11. He just grabbed the papers that have all of the information on it about what to do about side effects. It says Pfizer BioNtech and does not say anything about was given. It was just standard information. He just does not feel like he wanted to be that person who is not vaccinated. He wanted to be able to go places without a mask and wanted to feel safer. The event did not require a visit to the emergency room or Physician office. He started convulsing and tensed up for a second, then he passed out. He was not severely seizing or anything. After the shot, his head hurt a little bit but that was it. Right before it happened, everything was dark and hazy. His ear, he could not hear as well, everything was rumbly and muffled. When he woke up it quickly dialed down, from really muffled to hear everything and seeing everything fine. It was kind of like a quick switch. He fell asleep for a second and it felt like being teleported and everything was calm. Then, he heard his Mom screaming and that is when it came out of nowhere. He wanted to point out that this happened and put something in. He does not want this to happen to someone else. The outcome of the events was unknown.   Information about lot/batch number has been requested.
