Influenza virus vaccine, inactivated for Influenza Prophylaxis "For 24 hours after the high-dose flu shot (over 65), I endured chills, headache, stomach upset, stuffy nose, felt very, very sick all over, and ached and ached. Not a pleasant experience—yes, there are reactions to this shot—don’t let the medical profession fool you! I hope this was all worth it—"

Influenza virus vaccine, inactivated for Influenza Prophylaxis "I took the high-dose flu vaccine on 9/27 as I was planning a trip that required long hours in flight. Three days later, I had extremely bloodshot eyes with tearing, photophobia, chills, body aches, and headaches the like of which I have never had before. They seemed to be worse at night and early morning but varied in location and intensity. My balance was off (not good for a hiker!), so I was off-trail for a considerable time. Blurred vision, so I had my eyes examined with no changes there. Continued headaches with high blood pressure requiring an increase in my BP medication. This took me to the doctor and had an MRI on December 11. It was negative. Still having gait problems this far out from the vaccine and headaches. No one will ever convince me that this is a safe vaccine. I travel a lot and have had vaccines for typhoid, cholera, hepatitis A & B, pneumococcal, DPT in the last two years. Nothing wiped me out like this. I had to reschedule the trekking expedition I had planned for months."

Influenza virus vaccine, inactivated for Influenza Prophylaxis "I am 67 years old. Got this vaccine yesterday. By yesterday evening, I had chills, painful body spasms, and a headache. My husband had to help me walk. It was like having the flu! Did not sleep much last night due to spasms, headache, and chills. Mental confusion as well. I will refuse to take this vaccination again."

Influenza virus vaccine, inactivated for Influenza Prophylaxis "I’m 66 years old, and this is the first time I had the Fluzone HD. I was okay with the shot until bedtime when I experienced muscle aches, chills, and slight headaches (no fever), which lasted a couple of days. By the third day, all symptoms had resolved. I never experienced any swelling or pain in the arm where the shot was administered. I have always taken flu shots and had the 65 and over flu shot last year. This is the first time I ever experienced any side effects. I was informed that I would have some stiffness, which was an understatement! I’m in good health and not on any medications. I will stick with the regular 65 and older flu vaccination from now on!"

For Influenza Prophylaxis "The flu shot this year is something else. I have a fever, irritated throat, nose running, chills, nausea, etc. I always get my flu shot every year, but after getting this year's flu shot... I’m not going to be getting them anymore."

Influenza virus vaccine, inactivated for Influenza Prophylaxis "Received the egg-free shot on Friday, 10.16.20, at 6 pm. Due to the pandemic, I have been quarantined and work from home, so no chance of these symptoms being anything but vaccine-related. I haven’t had the flu since I was 6 years old, so this is the first time getting the shot. By 12 am, I had the sweats, by 3 am, I was in pain and nauseous, by 6 am, I was vomiting. Spent all day Saturday and Sunday in agony. My stomach is a mess, with head and body pains. I was able to eat bread Sunday evening, and Monday felt even worse with no appetite again. It’s now Tuesday at 3 am, and still no relief (currently sitting here in pain, nauseous, with chills and shaking). OTC meds don’t help. I’m generally a healthy 45 years old, exercise and walk 3-5 miles a day... I can barely walk to the bathroom. Pharmacist and MD are monitoring me. I will never get this vaccine again. I can’t believe this vaccine is considered safe."

Influenza virus vaccine, inactivated for Influenza Prophylaxis "I have been very sick for days following this shot. High fever, chills, terrible body pain, heart racing, and some of the worst headaches of my life. I won’t be getting the flu shot again. I was perfectly fine when I went in, four hours after the shot, I was in terrible pain and not in my arm."

Influenza virus vaccine, inactivated for Influenza Prophylaxis "While I did feel sick after the nasal flu vaccine one year, the flu shot itself never made me sick until this year. I still don't understand it. I usually feel a little dizzy the day of and a little run down for a couple days or so, but this time I felt pretty sick. The day of, I had moderate dizziness, which I attributed to lack of sleep and not eating when I had gone for a doctor's appointment where I opted to get the shot when they offered it. I kept explaining it away until the next day when I started having mild flu symptoms. I had the flu before, so I know what that's like. These symptoms were very minor compared to having the flu. I felt feverish, chilled, sore throat, body aches, no appetite, nausea. Still, advocate flu shot though."

Influenza virus vaccine, inactivated for Influenza Prophylaxis "Received this last week and felt a slight pinch. I never received the flu vaccine in the past, so I have nothing to compare it to. Not sure what side effects to expect, I was very tired later that evening. Did experience some slight cold symptoms, which I'm guessing is a side effect. There was no pain at all at the injection site, but a few days later it was a little red and itchy."

Influenza virus vaccine, inactivated for Influenza Prophylaxis "I get a flu shot every year. I have also been vaccinated with both pneumonia shots, gotten both Covid shots, and been boosted three times. The worst post-vaccine reaction to the shot has been tenderness of the shot site the next morning. I haven’t experienced any fever, chills, or body aches. I haven’t had any flu in years. Some winters have been accompanied by a cold, though none were severe. Some of these symptoms may have been flu-based but were mild enough to be considered only a cold. Presuming a reaction becomes a self-fulfilling prophecy."
