Well perhaps I took it the wrong way, it seems to infer that getting the shot will convey immunity which in turn would lessen the chance of transmission. Which would be contradictory to your statement.
Immunity does lessen (lessen, not eliminate entirely - therein lies the misunderstanding) the chance of transmission, which was the point of my statement (which you also took the wrong way).
Here's a hypothetical scenario that may help clear this all up:
Let's say you're a health care worker who is exposed to the flu all day long. You
are not immunized, so there's a definite risk of you becoming ill with the flu and passing it on to others (which can happen before you even know you're sick). The primary way a virus like the flu is transmitted is direct personal contact with someone who is also sick (you shake their unwashed and recently sneezed-into hand, etc, then touch your mouth - or they sneeze/cough in your general direction and you happen to breathe it in). Influenza is an airborne virus, so it is quite easy to become infected simply by sharing air with an infected person. Since health care workers share air with so many sick people on a daily basis, I'm sure you agree that immunization against such a contagious airborne virus as the flu is a good idea, rather than a conspiracy to implant RFID chips into American citizens.
Now let's say you're a health care worker who IS immunized. You can't become infected with influenza, nor can the virus live inside your body and be passed on through the air you breathe. The only ways you could pick up the virus and pass it to others would be through exposure to a contaminated surface or indirect contact with an infected person (sitting on a dirty tissue, tiny specks of mucous or phlegm on your clothing/skin from a sneeze or cough, etc). In order to then pass the virus on to someone else, that person would have to have very intimate contact with the contaminated body part or article of clothing. I'd imagine the most likely body part to become contaminated would be the hands. For you to pass the virus on to someone, you'd basically have to convince them to let you put your unwashed, ungloved hand in their mouth or nose - which most people would probably object to. For the virus to be passed from contaminated clothing would also require insertion into or direct contact with the mouth or nose.
I'm sure you can see the benefit of immunization in these scenarios greatly overshadows the low likelihood of surface-to-person transmission through an immunized middleman.
