So if you got sick with something you were immunized for it wouldnt be a shock to you, and you would think the vaccine was functional when injected?
We dont get polio. Period. Its not that we get minor cases and no one ends up on the iron lung so no one really cares. Polio was pretty much vaxxed out in this nation and most of the world. I know I did not receive a polio vaccine when I was young like my parents did. Why? Because it's gone. Heck polio is scary enough I wish I was vaxxed for it.
The MMR vaccine had similar impact. They are technically still around, and people get vaxxed, but people also dont get those diseases afterwards. Chicken pox and tetanus are the same. You dont get them. Yeah you may carry some around but are at no risk.
The flu is the only major exception, and as I understand it it's because it can "miss" and doesnt cover every variant of the flu. Not that it doesnt work.
@kiddiedoc can you weigh in? I, at least, am willing to accept your expertise on the matter if I am wrong.
Maybe there are a bunch of vaxxed I am not thinking of, or am just completely wrong. But my understanding was vaccine meant no sickness. Maybe sickness isnt the right medical term "impacted by the disease in a way that shows up as symptoms or being infectious to others" is how I am thinking about sickness.
