Mass disease prevention: The feasibility of airborne vaccines
The Scenario: A technologically advanced mother culture wants to manage mass outbreaks of virulent disease in its technologically regressed colonies, who are inclined to resist most of what the mother culture does, good or bad, as a basic principle. The mother culture, for their own part, treats disease control primarily as a political and economic issue -- not a humanitarian cause.
The Question: Is it feasible for the mother culture to engineer a series of airborne vaccines, and then have aircraft spray them on population centers? Airborne vaccines have been considered before, and we have spray vaccines even today.
If so, how effective could such a program be at controlling disease? What kind of infrastructure and technology might it require? Roughly how often would they have to respray to maintain reasonable levels of immunity? Would there be probable unintended consequences (considering factors like allergic reactions, pregnancies, people with weakened immune systems, etc.)?
