I never like to get a shot but I haven’t had the flu since I started taking them in 2008 after a flu that nearly landed me in the hospital. Right now I’m watching to make sure the new mRNA flu shot isn’t out. I don’t think it will be ready until next year.
I had the Hong Kong Flu 50+ years ago I honestly thought I was going to die AND was wishing I would die!! That flu put me IN BED for a month I thought I would NEVER feel like myself again, I was in my early 20’s OMG it was AWFUL!! I have NEVER had a cold OR flu since recovering from that 50+ years ago!! Never had a flu shot either!! When Covid hit I followed the supplement regimen my Doc gave me which was EXACTLY what most of us here were following, did not catch the damn thing did not wear a mask unless required by a store ect.
I tend to think the flu shot can be nominally effective against severe illness. A friend’s wife got it upon returning from Italy, said she was in bed for days and is just feeling better after 10 days.
