The flu shot needs to be updated yearly, and it mostly prevents hospitalizations and deaths. Seems pretty similar.
The flu vaccine is about 70% effective against getting flu[0], but it varies wildly by year. The Pfizer mRNA vaccine is about 50% effective against catching COVID five months later[1] (for the delta variant, anyway), but the third dose seems to push that up substantially.
