Clinical Course: Reported as, reporter stated, "The concern is that patient had the Prevnar 20 shot, 14Jan of this year, that's about 9 months ago and 24 hours after 14Jan patient was unable to walk, and they definitely confirmed that it was a reaction to this wonderful vaccine. They prevented me from walking normally for the last 9 months. Patient also not the only person that has that same reaction, patient have within, within 22 hours after having Prevnar 20, Broncho flu shot because he was worried, my doctor was worried about getting pneumonia and what happened was 23 hours later, I got up in middle of the night to just pick up the lap dog, the lap puppy and I couldn't even walk, I have a hang. I was terrified. I thought my god if I was froze or something and I were online the next day after inform my doctor and he explained probably what happened by any doctor and I am not the only that had this mobility issue ever since I have that lousy shot, I have had COVID-1, COVID-2 and the Booster by Pfizer had absolutely no problem with at all and those three and then all of a sudden about, I don't know, 5 months later it was after May of something of last year so I was okay. He wants me to have Bronchial pneumonia flu shot because he is worried that if you are over 65, you should have the protection against getting pneumonia. So, anyway I went ahead and I had the shot 14Jan2022 and within 24 hours my right knee was swollen three times its normal. Nothing else could have gone into my body to cause that and my right cap was screaming, burning, got awful pain. I went to an orthopedic doctor that day and he said I will get the fire out of this. This is from the Vaccine, and he said I will get the fire out of this I have got to give you cortisone shot (Intent: Treatment) to get you out of this pain and the flow in your right leg. And I have been through a hell of time. Because 4 other people that I know have had the same reaction, one is the veterinarian father. He said, just have some kind of reaction to one of these vaccines they give it everybody. I said how did you know about it. He said because my father had a reaction of Prevnar 20 and this going to be fiasco ever since he had it Then I talk to somebody else they said they have the same mobility issue and so I thought oh wonderful this reflects my gait of walking. I have been on fourth medicine (Intent: Treatment) for 6 months trying to get my walking normal back, I have to use the cane and I have had fourth medicine for taking, Just report, Just report this issue. Because I even know more, it could be veterinarian father. I would know that he had that reaction for Prevnar 20 must be told and I will never, I am coming out of this I am walking slowly now after 9 months of going through living hell with this Prevnar 20 shot. My doctor explained exactly what happened. He said this Prevnar 20 that I gave you, shot your Immune system up so high in your body because had the COVID (Intent: Pfizer COVID Vaccine) you had that, people are dying, last five months earlier before I had it. It got gotten up so high that attack your muscle and your joints and that's exactly. I will never have a vaccine from Pfizer as long as I live of any kind. I am done. My mother lived for 102 and she never had a Vaccine.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
