Suppose we have an adult in their late 20s who was never exposed to people and their germs, but now will be since they’ll be living among the rest of us. Obviously said person would need to be immunized for the same diseases we all are starting at birth since they’d be coming in contact with disease for the first time.
Would they be immunized on the same slow schedule that infants are, or quicker?
Basically I’m unsure if vaccinations are typically done over the first couple of years because babies are small or because their immune systems are immature. If it’s more the former, that wouldn’t be a problem with our hypothetical adult, but if it’s mostly the latter, his/her immune system would be just as immature. Right?
And speaking of their immune system being like a child’s…(weaned) babies and toddlers get sick all the time. Part of this is because they don’t have immunity to sickness since they’re encountering it for the first time, but they’re also kind of icky the way they touch everything and put dirty things in their mouths and make each other sick at daycare. If our person was taught proper hygiene upon their arrival, would they be sick all of the time still? How much of not getting our coworker’s illnesses is proper hand washing, and how much is that we’ve likely been exposed to their bugs before?
