Can i get a flu shot while taking antibiotics for an ear infection? i don't have a fever, have been fever free the past 24 hours.

Absolutely!: And please do. Although the flu vaccine is not 100% effective, it is the best way to prevent a potentially fatal disease, especially to those of highest risk. There are very few reasons not to get a flu vaccine, of which fever is one. For more info visit flu.gov

Yes: There is no reason to avoid a flu shot while on antibiotics for regular outpatient problems.
