Honestly though, that sounds... amazing. I've spent some of my life working in undeveloped, tropical areas. Because of this, I'm vaccinated against a bunch of diseases the average Western citizen doesn't worry about- Yellow Fever, Japanese Encephalitis, Tuburculosis and have seen first-hand the afflictions of the local populations who weren't vaccinated. Working in a clinic with sick and dying people, while being safe because I myself am vaccinated against the disease is kind of a surreal experience. While obviously the ideal would be a single dose providing lifelong protection, an annual booster still would make me incredibly grateful that I get to live in this modern, almost futuristic world of preventative medicine superpowers.
