how do you know you had the "flu"? unless you had a nasal swab to confirm the diagnosis of type a or type b influenza (the flu) then maybe you had another flu-like illness (there are many of them). people who self-diagnose themselves with the flu are often incorrect. besides if you did have the flu you only had one strain. the flu vaccine offers protection against three strains that may be circulating so i would vote for you getting the flu vaccine this year.
i'm just coming off having the severe flu and haven't had the flu shot this year. is it wise to still get it?
