Just because two things happen at the same time does not prove that one was causative of the other.
I am having the flu jab for the first time this year. I have never had a flu, not even in epidemic years when I lived or worked in crowded conditions where it was prevalent, neither has any member of my immediate family, so generally I do not bother.
However, I have read that although the flu jab is no protection against covid, the body's reaction to the jab leads to a strengthing of the natural immune system and under current circumstances, that is a very good reason for having it. So I will.
