If it was a certain point size I couldn't see it; This is a spontaneous report from a contactable consumer (patient). A 43-years-old male patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Lot Number: EW0158), via an unspecified route of administration, administered in Deltoid Left on 24Apr2021 (age at vaccine 43-years-old) as dose 1, single for COVID-19 immunization. The patient medical history included dyspnoea, experiencing trouble breathing and trouble getting up hills, decreased activity and asthenia all from an unknown date and unknown if ongoing. The patient concomitant medications were not reported. It was reported when he received his first dose of the Pfizer Covid-19 vaccine, the needle was longer and then with the second shot, the needle was shorter. He states, That is the only way I know how to identify which shot was which". He states "he intentionally sought the Pfizer vaccine over the others because it seemed to be the most vigorously tested, it was the first one, one that he was hearing the least about and that was my reason for choosing. So, in that context he went in hearing people had the first shot and were alright and second shot side effects were more serious, and they felt really bad for a couple days. He reports with the first shot he could feel a very deep tissue injection. In the arms was deep tissue sore from my elbow to my shoulder and it hurt to move, but what took me aback was the vision issue. My energy level was depleted to negative levels, walking felt like my feet were stuck in cinderblocks, walking down the hallway took me 20 minutes to get down the hallway. he remembers being on the text meeting for work and I'm telling them he at 35% now and if people say the second is worse than he need to take days off. My thinking was cloudy, felt unbalanced, legs felt weird like my feet were in someone else is shoes, no stamina, wanted to sleep, no energy. he was still quite tired with low energy the next day. A couple days after the shot he had a significant change in vision, was pretty much unable to read anything. If it was a certain point size, he could not see it. he could see objects, driving was not an issue, but reading emails and newspaper were difficult. Thank goodness for the expandable screen on the iPhone. But then, my vision almost snapped right back to 90 to 85 % normal after second shot. It was definitely a shorter needle. Felt superficial, didn't hurt near as bad, effects milder and were sort of spread out over a longer time. The first shot was compressed into 4 to 5 days. he was on the back for 5-7 days. he did not have near the change in stamina after second shot. Just a couple days ago I started to feel like I can work out again. he had light symptoms: a hint of chill, hint of a muscle ache, headache, my vision popped back into place, they were a hint and then disappeared over a week and a half and now he is feeling like he normally had been, but he is turning 44 next week so that might have something to do with. he states he question is if indeed I was administered the shot in opposite order, should he have it done again. Am he actually vaccinated or not, He states so it felt thicker with the longer needle, thought it was different substance deeper into the muscle he states he did not know if that was part of some instruction of which would come first or why it would be at different depths, Why would it feel thicker and feel deeper the second time. He Before corona hit, he was experiencing trouble breathing and trouble getting up hills. His activity and stamina were diminished. After getting the corona vaccine it has that magnified by 1,000.
