My husband has a sinus infection. Can he still get a flu shot now or does he have to wait until the infection clears up?

As long as he is not running a fever it should be fine.

I, (stupidly) and my wife put off getting flu shots in 2010 because I had similar symptoms and both of us spent two weeks in bed with swine flu. When I finally got the shot, they told me exactly what J_9 said.

Edit: I clicked helpful on J_9 post and the word helpful disappeared and inaccurate flashed twice. I have no idea what might have been recorded if anything. In original. This site is scary.
