For COVID-19 "I was forced to take this snake oil back in 09/2021 to keep my job. I developed blot clots in my right leg, and it swollen up twice the size of my left leg. Tore my liver up, started bleeding from moderate liver disease. Had to take blot clot thinner for my leg, which made me bleed worse. Ended up getting a blood transfusion and now have to get fluid drained off my stomach every 10 days. Prior to taking this, I had moderate liver disease, now I need a transplant and am too old to get one. Someone should be liable for this thrown together vaccine, and since the government forced it on everyone, why not them? Hope there's a lawyer out there with some courage to do it. I'm all in. All that happened to me is documented to the hilt."

For COVID-19 "I received my Moderna COVID booster yesterday. Within 3 hours after getting this, I had a fever of 101 with chills all night and continuing today. Every joint in my body has severe pain. My head is busting. My arm in which it was given turned red from my shoulder to my elbow, with swelling so bad that I can't get into a short-sleeve top. Now I am nauseated also. I called the pharmacist who gave the immunization, and she said all these side effects should only last 24 hours. It has been 26 hours since all these side effects started. I don't have a weakened immune system."

For COVID-19 "I had no reaction to first shot J&J. I was advised to go with Moderna for the booster on December 8, 2022, and ever since, I have a serious issue with electric shock/pins and needles feeling if my body gets too warm or if I take a shower too hot. It's like being hooked up to electricity, and the voltage starts low and gradually goes high. Then, in seconds after I strip from clothes to cool off, the voltage goes down, hitting me over different parts or radiating through my body. While put on Prednisone for a week, it stops during that time. Once done, and 2 days later, symptoms return. Put back on Prednisone for a second round, and shock symptoms go away, but once the week of Prednisone is done again, symptoms returned. I was told the shot may have triggered inflammation in my body or neuropathy. This is during winter months - spring, I wonder will it intensify in the summer temperatures."

For COVID-19 "20-year-old male with severe asthma (2 or more asthma attacks per day), and probable COPD, allergies with chronic urticaria, and lupus. I take 7.5 mg prednisone daily. Reasonably scared of the coronavirus. My vaccine experience: First dose: pain and swelling at the injection site, upper arm felt very sore the next day, still was a little sore the day after. Second dose: more swelling than the first dose (most of upper arm muscle felt a little swollen with slightly swollen lymph nodes in the upper arm and shoulder), upper arm felt sore for a few days. In conclusion, I had a sore and swollen arm after each shot with slightly more swelling after the second dose. A sore arm is a small price to pay for protection against this deadly virus that I know would likely kill me."
