The reporter stated, "My daughter she is 8 years old, she had her second Pfizer COVID-19 vaccine yesterday (later date of vaccination of second dose clarified as 23Sep2022) at her pediatrics and I was just reading over the paperwork. She has just some, she has just a couple of the side effects that are listed on the paperwork and I just happen to see where you know, it said to go ahead and report those and so, I thought I would call in and do that. She has the injection site swelling and injection site redness. This I do not think is listed but it is itching and it is a little warm to the touch, if I touch it you know, sort of warm but it is itching her but she is scratching at it you know and it is rather large in size, the redness. She seems to have a decreased appetite that she has had. She had very 'little' diarrhea all morning since she is been up probably at, she has been up since probably 7:30 am and probably it started at about, I would say 9 am and it is 12:30 pm here so I believe it is well, I am not sure, I think we are eastern standard time I am not sure. Probably she had that for about 3 and half hours." Reporter stated, "She did had the injection in her leg this time she went ahead and had it, last time it was in her arm. She went ahead and just got it in her leg this time so you know, if that is makes a difference. We did that just because she was getting a flu shot (Further not clarified hence suspect captured as Unspecified Shot) too and we had it put in her other leg and just because you know her walking around and stuff we thought that. You know it might cause less pain say of the flu shot and being in the other leg. So, we just got one put it in each leg so, that was you know the reason for that." Reporter stated regarding lot details that, "The first dose was FL8095 and this dose yesterday was FL9095 (clarified as lot# of second dose). Yes, I am trying to see if, because I am trying to read yes, because it would not be the same for sure. I am trying to read the nurse's handwriting and it has to be 9095, it could not be 8095 for the second one, right. Right, they could not be the same dose# right." Patient did not have any medical condition and was not taking any concomitant medications. Reporter stated, "No laboratory test. She was actually there just for her 8 year old wellness checkup and just went ahead and got the vaccinations while we were there. Treatment for AE; Reporter stated, "No and like I mentioned though she did get her flu vaccination yesterday as well in her other leg. He did not have the lot number available with him."
