For COVID-19 "I felt out of it for a couple of weeks. I had no appetite and had a general feeling of being unwell. My daughter had a fever, chills, and then came down with the shingles soon afterward. It's hard to know if it's effective or what long-term problems there could be with it."

For COVID-19 "This product should be withdrawn. Within 48 hours of administration, I experienced severe and prolonged side effects. Tiredness, chills, blurred vision, dizziness, and general nausea. This lasted for 6-8 weeks. Shortly afterward, my blood pressure began to read higher consistently. I am also experiencing intermittent heart palpitations. I then got COVID 6 months after the vaccine. I have also recently had another COVID infection. So both ineffective and unsafe. I expect to be on long-term medication to lower/regulate my blood pressure, thanks to this product. It should be avoided at all costs."

For COVID-19 "Received the J&J one-dose primary vaccine ~27 hours ago. Needed the one dose for travel and work purposes and would not have enough time to do a 2-shot series. My doctor approved me to get this as I’m a 40+ female (higher risk for clots). The pharmacist told me to expect the shot to hurt due to the muscle location and burn during administration. That was true. She did advise me to move my arm a lot to prevent soreness. If I would get any side effects, they would occur within the first 24 hours (most likely the first 6-12). Six hours post-vax, got chills. A couple of hours later, got severe body aches. Temp maxed out at 99.1. Had a horrible night unable to sleep due to body aches and chills. Honestly, this was akin to when I had an actual Covid infection 6 months ago. Aches and chills ended within 12 hours, but feel tired and rundown today with a bad headache."

For COVID-19 "Mildly sore, tender arm for several days. More fatigued than usual for a few days. Otherwise, zero ill effects. Hopefully, this will combine with my daily immune system-boosting regimen to improve my defense against SARS-CoV-2."

For COVID-19 "I had a great experience with Janssen COVID-19 Vaccine. Fortunately, I only experienced minimal soreness in my arm for a few minutes and zero side effects. Also, I recently contracted the Covid-19 virus and the J & J vaccine fought it off pretty well -- less the booster shot too. Although I was a bit concerned about my health, I did not experience any serious complications at all (a few days of coughing, runny nose, body aches, and low-grade fever)."
