And if the CDC decides that the most common type of influenza is the same as last year, you will still need to refresh it, regardless if you got the same vaccine last year.
Quite often the strains mutate in the wild and the flu shot is useless.
Not something anyone “needs” unless your employer compels you to inject it.
