A 34-years-old male patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE), intramuscular in Arm Left on 17May2021 (at the age of 34-years-old) (Lot Number: EW0187) as single dose for covid-19 immunization. Medical history included higher than normal blood pressure, about 2-3 weeks ago, his blood pressure was very high due to really crazy stress in his life and eating terrible; headaches, smoked marijuana, drunk vodka, sometimes he had a sensitivity to needles, sometimes he will have angst or nervousness with needles, Sometimes he got a little queasy with the sight of needles and just had a ton of dental work done. Concomitant medications included cetirizine hydrochloride (Generic Brand Zyrtec); caffeine, paracetamol (EXCEDRIN) taken for headaches. He explained he took Generic Brand Zyrtec which he had been on for years now and he took Excedrin for headaches when he got them. Those were basically the only medications he took really. He hadn't had any type of vaccine. He previously had a tetanus shot about 10 years ago for Immunization. There was no previous immunization with the Pfizer vaccine considered as suspect. There were no additional vaccines administered on same date of the Pfizer suspect. There were no vaccinations within four weeks prior to the first administration date of the suspect vaccine. The patient received his first dose of the Pfizer BioNTech COVID 19 Vaccine on Monday, 17May2021. Within 3-5 minutes of getting the vaccine, he had a really crazy reaction. He remembered looking at his wife and she told him he was having mild convulsions as he was sitting in the chair in May2021. He was kind of shaking in May2021. He turned ghostly white and he began sweating profusely in May2021. He mentioned that her wife said that he was not conscious for around 5 minutes and was "snoring with eyes open" in May2021. He added that he was "fighting to stay awake" for around 15-20 minutes after that. He blacked out. All he remembers was that he was trying to fight off tunnel vision for a very brief time in May2021. The pharmacist continuously checked on him. The lightheadedness and feeling like he was going to black out lasted 15-20 minutes in May2021. They put him in a chair and told him to elevate his feet, but the caller explains he could not elevate his feet. He had his feet in another chair in front of him. He couldn't get comfortable, he was sitting down. He was restless, lightheaded. He kept feeling like he was going to pass out. So, then he tried to stand up and walk a little bit. He only made it 5 steps. So, he sat on the ground and laid down. He laid on the ground, flat on his back, and put his feet in a chair, which was about 2.5 feet above him for about 15-20 minutes. He started to feel better. He still felt very tired and weak in May2021 but he was able to stand up and walk and go home. He hadn't had a reaction since. He had had no other symptoms besides just a sore arm in May2021. He confirmed he recovered completely from his experience when he was administered the vaccine. He came home from the vaccine facility, laid on the couch and watched TV for a couple of hours and then fell asleep for 3-4 hours. He was tired, but he felt completely fine. He had no lightheadedness, no dizziness. He also wanted to add sometimes he has a sensitivity to needles, but he didn't when he received the COVID vaccine. Sometimes he will have angst or nervousness with needles, but he was actually excited to get the COVID shot. He was even comforting his wife and was telling her everything is going to be okay. He wasn't worried about the needle with the COVID shot. Sometimes, he gets a little queasy with the sight of needles, but he saw the needle and he didn't feel faint or angst when getting the shot. He just had a ton of dental work done, where he had huge needles shoved in his mouth and he didn't feel faint or anything. He really wanted to get the second shot to finish the vaccination series. He did kind of believe he had a reaction, he was not trying to play it off and say "oh I got the vaccine and passed out". He knew himself and knew what it's like to faint and this experience just felt different. He believed he had a reaction. He never felt tunnel vision that strong in his entire life, it felt like being punched in the face. Since those 2-3 weeks, his stress load had gone down and he had had a drastic change in his diet, so his blood pressure was reading much better now. This past Monday, 17May2021, when he received his vaccine, his blood pressure shouldn't have been that high.  The EMT's did come before he left and because he passed out his blood pressure was low at 100/60. When providing the Lot number off of his vaccine record card, the patient explained the last digit was either a 7 or a 2, he can't read this person's handwriting", however, he eventually confirmed the number was a 7.  The events did not require a visit to Emergency Room and Physician Office. The outcome of event tired was unknown and the outcome of the other events was recovered in May2021.
