Not a coincidence I’m my opinion. I was very hesitant to get my Covid vaccine and I got one last Thursday. I had a flareup three days later so bad I couldn’t get in and out of bed or use any of the bathroom facilities myself for about 48 hours. It was just awful I had to increase my prednisone to a high dose after I was down to 5 mg and I’m on the chase. So when I say no coincidence if the flu shot did this to me and then the Covid shot it’s something they’re putting in the vaccines. Just my opinion
