"I had a bad reaction to this vaccine within 2 hours of the injection. First, I became congested, and a cough developed shortly after the congestion started. Then came a headache, followed by nausea and vomiting. I felt feverish and basically felt like I had the flu. I felt much better the next morning but had to stay home from work because I wasn't feeling well enough to go anywhere. By late afternoon, I was nearly back to normal. I have never had a reaction like this to the regular dose of the flu vaccine. I will not take the high dose again."

For Influenza Prophylaxis "October 8, 2021, I received the HD flu vaccine for the first time. I am 71 and in good health. After 6 hours, I developed a headache and severe muscle and joint pain. Terrible back pain and couldn't sleep. Low-grade fever the next day and still aching, headache. I will never get this type of vaccine again. Never had a problem with the regular flu vaccine."

For Influenza Prophylaxis "My doc told me to always get the flu and pneumonia shot. In the past, I almost died from pneumonia, hospitalized for a month. So every year, I go and get the high dose for flu. I'm a 68-year-old. I'm almost at death's door, almost. Every time I even went to the ER several of those times, the ER doc asked if I got the flu shot and I said yes. I asked him why I feel so horrible when I was vaccinated against the flu, and his reply was at least it kept you from dying! Well, I couldn't wrap my head around this. So the very next year, which was 2021, I went and got another flu shot that year. Well, believe me, I'm done with them, I'd rather take my chances. Last year, at the height of the pandemic, I thought okay, I better get some protection. It wasn't long until I fell ill with nausea, 103 fever, agonizing headaches, and muscle aches. Called the doc, said oh it could be COVID, get tested... no local testing available. So I quarantined at home. I know it was the flu and not COVID, no coughing, no SOB. Never again!"

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."
