Consumer stated, I am having side effects from my shot 3, from Covid-19 Vaccine (Pfizer Covid-19 Vaccine). It was not too bad. I just wanted to report what I am feeling. Consumer stated, Well, pain in the injection site which was normal, a bit of fever, chills like I am cold, joint pain, body pain, like if I touch my body it kind of hurts a little bit, fatigue, I guess, loss of appetite but at the same time you are hungry and I guess like I cannot walk too much because I tend to fall like obviously my joints kind of like bother me and I think, I guess it was nightmares, sleepy like tired, I get thirsty. It was like relaxing away. I think that my immune system and I think that is like overall what it is, it is more off this Covid shot. So, it was I think that the second shot was like way worse. This was not too bad. When clarified if the consumer receive the third dose of Pfizer Covid-19 Vaccine, in response Consumer stated, I got the first one, the second one and then I got a new one, a third one. That was the new booster that was happening. I think so approximately I would say 8 hours after the shot. When probed for the safety report, Consumer stated, And also that the symptoms are less severe than the second shot, if that helps. So, the first one was kind of, I am feeling kind of like the same effects that I got from the first one. But not entirely. So, it is like it was like alright and then it was like really bad for the second one and now it was like not too much. I was having a little bit of nausea that is the only thing. But that is the only medication (Unspecified Medication) I just started. So, I think that was because I have not eaten anything. Start date of events: Consumer stated, the first shot, let me think about it. So, the first shot. It was in December and I started having, I remember being, I think the symptoms were kind of same. I take the vaccine; I was off for two days after and I was like sleepy and I have just a little bit of fever and stuff like that. It was like the same that I am having right now. But not bad. The second dose, three hours after I got it I was feeling sleepy. I slept, I believe like 20 hours. But like symptoms were like I would sleep that much. But then I was like waking up. I normally play in a video game & I was feeling like that something is happening and also like my body was burning, my nostrils were hurting, my joints felt like, the same symptoms and I was like waking up, just drinking water and going to the bathroom. Drinking water- going to the bathroom, drinking water- going to the bathroom and then just like sleeping. At the same time sleeping- water- bathroom. Consumer stated, My left arm. All of them have been in my left arm. Consumer stated, No, I was recently diagnosed with HIV. So, that is why I got my first shot. So, I was recently diagnosed with HIV for my shot no.3. So, that is why it was this past Monday. I guess you can say 16Aug or Aug17. Consumer stated, I just started the HIV medication. I mean I take the other ones. But I do take any other medication when I took the vaccine. I have the medication. But I just started it yesterday. After you like always after my shot. So, the medication is not showing any side effects yet like this. This is how my immune response reacts usually. So, does not have to do anything to do with it. Laboratory work: Consumer stated, Yes, I got blood and I got urine. Blood & urine. I am sorry I just had another thing to add, I had an antibacterial injection like antibiotic, I mean, and I got an antibiotic injection. But it should not be that. Only it is like side effect of and many medication, it was just like may be like diarrhea. But it is still nothing to do with my immune system. The patient did not receive any treatment for the events. The outcome of the events was unknown.
