I didn't have near the change in stamina after second shot; A hint of chill; Hint of a muscle ache; Headache; The blurriness seemed to snap back once he got his second shot; This is a spontaneous report from a contactable consumer or other non hcp (patient). A 43-year-old male patient received second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Batch/Lot Number: EW0183) via an unspecified route of administration on 15May2021 as dose 2, single (age at vaccination 43-year-old) for COVID-19 immunization. The patient medical history and concomitant medications were not reported. The patient previously received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, lot number EW0158) 1st dose on 24Apr2021 (age at vaccination 43-year-old), administered on left shoulder, for COVID-19 immunization. The patient experienced I didn't have near the change in stamina after second shot, a hint of chill, hint of a muscle ache, headache, the blurriness seemed to snap back once he got his second shot on an unspecified date. Caller is a consumer (43 years old, male) who is inquiring about additional information for revaccination following getting a complete 2-dose series of the Pfizer covid-19 vaccine. Caller reports 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. Caller reports with the first shot I could feel a very deep tissue injection. In my arm 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. I remember being on the text meeting for work and I'm telling them I'm at 35 percent now and if people say the second is worse than I need to take days off. My thinking was cloudy, felt unbalanced, legs felt weird like my feet were in someone else's shoes, no stamina, wanted to sleep, no energy. I was still quite tired with low energy the next day. A couple days after the shot I had a significant change in vision, was pretty much unable to read anything. If it was a certain point size I couldn't see it. I could see objects, driving wasn't 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 more mild and were sort of spread out over a longer time. The first shot was compressed into 4 to 5 days. I was on my back for 5-7 days. I didn't have near the change in stamina after second shot. Just a couple days ago I started to feel like I can work out again. I 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 I'm feeling like I normally had been, but I am turning 44 next week so that might have something to do with. Caller states so it felt thicker with the longer needle, thought it was different substance deeper into the muscle. Caller states I didn't 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 enquired. The number on my card are different than other people's. I had the opposite side effects than other people had. I just want to make sure what they're doing is correct. Caller states again, I just want to make sure it was safe or if there was some other element I should know. Blurriness: His first shot was administered on 24Apr2021.
