An 80-year-old male patient received second dose of bnt162b2 (COMIRNATY, formulation: solution for injection, Batch/Lot number: FC3184) via unknown route of administration on 15Sep2021 (at the age of 80 years old) as DOSE 2, SINGLE for covid-19 immunisation.

On 30Jul2021, the blood test for Covid antibodies showed antibodies. Historical vaccine included first dose of bnt162b2 (COMIRNATY, formulation: solution for injection, Batch/Lot number: FC3181) via unknown route of administration in left arm on 23Aug2021 (at the age of 80 years old) as DOSE 1, SINGLE for covid-19 immunisation, after first dose, was totally whacked out and was in bed for 24 hours, Had absolutely no energy the following night; I stayed in bed for 24 hours because I was just totally exhausted, When the first one totally wiped out so, expected that wasn't surprised that, he was in bed for 24hours. On 16Sep2021, It was reported that patient was fine after first shot and after receiving second dose on patient had absolutely no energy the following night, he stayed in bed for 24 hours because he was just totally exhausted he was in bed for 24 hours, but what did surprise him about the second shot after about 20 hours he got up to try and use the bathroom and realized that his limbs, legs and arms were paralyzed, he had no muscle use on 16Sep2021, his legs collapsed and he fell on the floor on 16Sep2021. He couldn't get on knees so laid on the floor for 4 hours on 16Sep2021 because he lived alone. he was hoping it would just pass on its own and it did pass after 4 or 4.5 hours, he slowly started getting strength back and then Thursday morning during the day this happened. It was yesterday, Thursday, probably about 7:30 at night. His legs collapsed and found that he had no use in his arms or legs. It has nothing to do with us, but when his legs collapsed, he hit the top of his head and has a big bruise on his forehead on 16Sep2021. It passed after 4 and a half hours. That was his best guess. It didn't pass immediately, because he kept trying to get up during this whole process. There is no way, he waited about 15 minutes and tried again after about 4 and a half hours, he thinks he was barely able to just move and he collapsed again. He was finally able to do it. During that whole process, he was trying to get up. All he could do was just be prone and he was on the floor and wanted to get up. He tried to get up but couldn't do it. After four hours of not being able to get up, he was able to use his arms and legs, but barely. It was ultimately a process. He worked himself up and now it is like unsteady and said he was ok and to take it easy over time. It wasn't like 1 minute he was prone, then another minute, he was standing up and running around. It didn't work that way. After about 3 hours, he started dragging himself the best he could and got to some tile area where he was on his knees and when trying to get up, he got a bruise there. It is still a little sore there now but, that has nothing to do with the vaccine. Clarified the also had a bruise on his forehead from the fall. He had prescriptions and supplements but clarified that he did not take anything specifically for these symptoms. He was 90 percent recovered and still a little sore from where he fell. His knees are a little sore and his arms are a little sore. Other than that, he was ok. It was reported that he got vaccinated and he started getting really sleepy on an unspecified date. The outcome of the events big bruise on his forehead, sleepy and had absolutely no energy was unknown and other events were recovering.  No follow-up attempts are needed. No further information is expected.
