"Yes, because unvaccinated humans lack immunity. A single imported case could spread rapidly through an unvaccinated..."
That's assuming there would be an imported case. Travel restrictions can solve that. That's how we handle other US eradicated diseases, such as yellow fever.
You'd still need mass vaccination campaigns because immunity wanes over decades. If it resurges, it will rip through the elderly, especially nursing homes.
- beej71 9mo ago"such as yellow fever" Yellow fever is spread through mosquito bites and polio is spread person-to-person. An imported case of yellow fever is nearly impossible to spread, while an imported case of polio is virtually certain to spread. Sorry, but it's simply naive to think that in today's global world we would not import polio. It's already happening right now in the US. The only thing stopping the spread is our current high vaccination rate. You'd have to cut travel to zero in both directions to stop it.
