Is it dangerous if I got a flu shot while I was sick with a sinus infection and was one antibiotics?

Probably not. But there is some evidence that getting a flu shot when you have an illness with a fever might make the flu shot less effective. Best idea is to wait until you're better.

Urban myth! Influenza immunization has no effect on the immue system, except to help make the recipient immune to flu. It doesn't cause a minor case of influenza, fever, or anything like that; and it doesn't raise the chance of sinusitis or anything else. It is irresponsible to not get vaccinated against flu on account of such things. OTOH, we're almost at the end of flu season, so it may be too late to help.
