As a young, healthy person you don’t get the flu vaccine to protect yourself, you get it to lessen the chances that you’ll pass on the flu to someone elderly or immunocompromised for whom the flu is often deadly.

This is how vaccines work toward public health. Not by preventing illness in all cases, but by lessening the pool of potential cases to ease the health burden on the population.

It’s good practice as a citizen and a neighbor to get vaccinated.
