“Seth material” search engine (Jane Roberts)

(Pause at 10:42.) Give us a moment… In your society scientific medical beliefs operate, and a kind of preventative medicine, mentioned earlier, in which procedures [of inoculation] are taken, bringing about in healthy individuals a minute disease condition that then gives immunity against a more massive visitation. In the case of any given disease this procedure might work quite well for those who believe in it. It is, however, the belief, and not the procedure, that works (louder).²

They do not “worry.” They do not anticipate disaster when no signs of it are apparent in their immediate environment. On their own they do not need preventative medicine. Pet animals are inoculated against diseases, however. In your society this almost becomes a necessity. In a “purely natural” setting you would not have as many living puppies or kittens. There are stages of physical existence, and in those terms nature knows what it is doing. When a species overproduces, the incidences of, say, epidemics grow. This applies to human populations as well as to the animals.
