I work in healthcare, and am mandated to either get a flu shot, or wear a mask at work.
I get the flu shot. I know there is a little risk, and I know it won’t protect me against all variants, but I get the vaccine.
I have never had the flu that I am aware of (knock on wood) but it looks so miserable, that if it keeps me from getting even one episode of one variety, that is five minutes well spent.
I work in healthcare and have had the flu twice. Once as a young person and once as a not so young person. I am first i. mine for the flu clinics every year to get my vaccine. It may not prevent the flu in every case but it likely lessens it if you do get it. Some years are better than others.
