It’s basically a numbers game. With a vaccine the flu can’t spread through your body because you have immunity. Meaning your body can fight of the flu so you don’t get sick/have symptoms (or at least all of that is greatly diminished). Since the flu can’t spread in your body, there is less flu in you for you to spread to others.
So more people vaccinated means less viral load in the community which means less people spreading and therefore getting the flu.
I guess that does kinda make sense, less viral load in the commumity = better. I always thought that, because it might only protect against 80% of the flu strains out there (or however good we guess for the season), that herd immunity can’t be achieved and there was no point
I definitely never heard of it presented as a measure to protect people around me
