Don't flu shots work by giving you a mini-flu?

Only the nasal spray flu vaccines contain live virus.

The CDC is recommending against the nasal spray this season, so chances are you'll get a shot, which contains only dead virus, which can't cause anything you'd describe as "mini flu" as a result.

The nasal vaccine has been deprecated for a long time now, I'm not sure you can get it anywhere ATM.

The flu shot seems to put me a bit under the weather for a couple of days after I get it. I don't have the flu, but I'm not 100% either.

That may be true for many people, but what about young children and the elderly?

Does the flu vaccine count as exposure?

that is exactly what the vaccine is. exposure to a inactivated flu virus.

then, lots of research and crossed fingers that hope any flu's you are exposed to are the ones that you vaccinated against.
