I understand your concerns about different vaccines; however, the flu vaccine is a dead virus and you can't get the flu from it. Side effects from the flu shot can be aches and a low-grade fever; but those are just that - side effects. Now if somebody gets the nasal form, that's another story - it's a live virus.
If people only knew or could see how many people die each year because of the flu and/or pneumonia, I'm sure they'd be more prone to get the shot and save lives - possibly their own.
