I got mine last October and so far so good. Knock on wood.
My wife and I have never had one. I’ve not gotten the flu in decades. My wife got it three years ago. It was a very hard four weeks. My brother got it at around the same time in Seattle (we’re in Kentucky). He had a flu shot. He also went to the hospital because of the seriousness (it was the same as my wife’s).
His lasted six weeks.
My wife and I trust the Lord with healing and He has been faithful.
