I took my first flu shot 22+ years ago and have had the chronic form of guillain-barre syndrome ever since. I won’t be taking a Covid jab.
I stopped with flu shots around 2013. I kept a journal of when I would experience illness or allergic reactions to track potential seasonal triggers.
I always became deathly ill after flu shots, as if I had taken a full viral load.
I skipped the next year and did not become ill, although still had to watch for my abundance of allergies. Always had issues since my early teen years.
So never having taken a flu shot again, I found I didn’t become sick from the flu since.
So hard pass on that shot. I do keep up with my boosters for the old known plagues with proven vaccines though.
