Historical vaccine included bnt162b2 (PFIZER BIONTECH COVID-19 MRNA VACCINE Solution for injection Lot Number was not reported) via an unspecified route of administration on an unspecified date as dose 1, single for COVID-19 immunisation and felt a little tired. On an unspecified date Feb2021, it was reported that my husband and I had second shot of vaccine on Saturday, we were fine on Saturday with no reaction at all and on Sunday morning, my husband fell in the shower, I guess maybe he was a little dizzy from the vaccine and then he was fine on Monday, then he had weakness in his leg, he was 89 and last night it did not hurt him not in his shoulder and or arm anymore but it hurt him on the side of his cheek in his jaw, and then he could not get up he was not able to stand. This morning he was able to get out the bed and stand now he feels better that he did yesterday, but I wanted to know, I know it were about joints this can happened about few days, but I wanted to know does it would be common for him to feel like it hurts him on one side of his mouth, will that be an side effect as well. I washed his mouth with water. Now what are going to check on that and find out. We did not had anything last week except a little tired, 3 weeks ago for the first one and I am m perfectly fine I feel chilled like for 2 hours and thats all, but he was much better today but I want to make sure I read the book that they gave me, and I want to make sure that it was just a side effect and that he will get better. The only problem was that he had weakness and could not stand up on his legs and he had pain in his cheeks. I dont know if I had to take him to the dentist and I need to find out if this is a side effect. The patient underwent lab tests and procedures which included laboratory test resulted as normal o an unspecified date. The clinical outcome of the events was not resolved.  Follow-up attempts are completed. No further information is expected.
