I think cleanliness and avoiding sick people are the best defense for avoiding the flu. Hmm, sounds familiar. I wonder what % of people get the flu vaccine each year. Less sick = less distribution of virus cells.
I don't think it's that simple. The vaccine keeps you from getting sick. It doesn't keep you from transporting the virus around with you and spreading it.

Uhhhhhhh.......yes it does. Now technically a vaccinated person could touch something with the virus then touch something else and ‘transport’ it that way, but that’s not the point. That same person can’t spread the infection because of anything going on in their body over the course of time.
