But vaccines themselve are not needed if you live in an otherwise healthy and clean environment.
If you live in a third world country and drink and wash in what amounts to raw sewage, then yes, get vaccinated. (of course here where vaccines would help, they can't afford to get them)
No one lives in an otherwise healthy and clean environment, except maybe Bubble Boy, and look what happened to him. Do you think no one travels anymore? That no immigrants come to our country who aren't vaccinated? And actually, most vaccines don't do anything to prevent disease from drinking raw sewage. Most vaccine diseases are air born or droplet born and just being in the same classroom with someone with one of these diseases will give it to you if you aren't vaccinated.
