For COVID-19 "I had the Moderna COVID jab Fri 7/10/22 at 10:30 am. By 6:00 pm, I started a sore throat. I had a headache, feeling unwell, and it got worse over Sat and into the early hours of Sunday. I felt I was on my last legs, unwell even today, Wed 12/10/22. I am chesty and tired. Before the jab, I was a healthy 73-year-old in the UK. Next time I am invited for a booster, I will tell the doctor no thanks."

For COVID-19 "I received my first Moderna vaccine 2 days ago. I’m a healthy, 39-year-old woman. I walked into my appointment feeling good and left feeling unwell. 10 minutes after the shot, I felt heart palpitations for only a few seconds, then they went away. Negative side effects I've felt so far: dizziness, disorientation, lethargy, muscle pain, joint pain, nausea. Generally, I feel unwell and regret getting vaccinated."

For COVID-19 "Yesterday, my wife and I had our Moderna COVID jab. This being the 4th one (October 2022). My wife is 65, and I am 71, in general good health. We had not had Moderna previously. Within two hours, my wife started feeling unwell with tiredness, chills, mild aches, and pains. She went to bed. I was fine and had no effects until I woke two hours ago at 3 a.m. with severe joint pain and a headache. My wife also woke with worsening aches and pains. We both took paracetamol and hope that the symptoms improve."

For COVID-19 "I had this as a booster in Nov 2021 after having had AstraZeneca 1 and 2. AZ was fine. After Moderna, I was ill overnight and very tired the next week or so, aching joints, etc. My sense of taste was severely impacted and has not fully recovered 10 months later, and I get periods when I suddenly have no energy at all. I caught COVID in August 2022, which wasn't bad at all, but the week after I was negative was bad... exactly the same symptoms as post Moderna - tired, aching joints, etc. Sense of taste didn't get any worse."

For COVID-19 "Had the booster Thursday the 14th. Didn’t feel the injection at all. By the evening, my arm felt heavy, and I felt tired with a bad headache. Day 2 and 3, terrible headache which even paracetamol cannot shift. Aching all over, heavy sore arm. Can only hope that I start to feel better soon."

For COVID-19 "I had both injections spaced 1 month apart. I have an autoimmune disease. First vaccine injection, I felt incredibly tired and a seriously painful arm at the injection site, lasted 3 days. Just had the second one a couple days ago, with worse side effects. Constant fever of 101-101.9, severe, excruciating pain in my hip joints and my thigh muscles, severe fatigue, gas, a bad bloody nose, lack of appetite, and nausea, weakness in both arms and legs, and dizziness. I also developed a large welt at the injection site and a rash covering my shoulder down to just below the site and near all the way around my arm that’s red, itchy, and hot. My arm hurt 10 times worse. Today is day 3 for me, and I’m just about over all the really bad effects, only feeling very fatigued. With all that being said, I have an overactive immune system and many other severe physical illnesses. This was fully expected. All I have to say is being sick for 3 days beats being sick for 2 weeks to a month if I did get COVID."
