The flu vaccine reduces severity and likelihood of catching it as well (which can serve to protect vulnerable populations). Your own personal chance of death is not all that matters.

Getting it yearly may also reduce the risk of other related conditions e.g. https://www.uth.edu/news/story/uthealth-houston-study-flu-va...

It's nearly risk free and it's definitely worth it even if all it did was decrease the severity of flu if you catch it (and it does more than that).
