i took the salk vaccine. have some older community members who didn't. it was easy to tell who did, and who didn't.
but beyond all that yesteryear stuff, even if a "guessed at" vaccine is 10 percent effective, it's better than none.
i figure if they get it 50 percent right, they're hitting it out of the park.
i haven't taken the shingles vaccine, havent had it either.
can anyone imagine allowing all humans to go "free-range" and deny them all treatments? (you know treatments can be dangerous, have side effects).
i think going free range would toughen up the human genome. make it better able to resist alien diseases arriving on meteorites, etc.
