In this case the virus is a result of one of the polio vaccines.

Whomever brought it would very possibly have done the right thing and gotten vaccinated recently, but the live attenuated polio vaccine very occasionally leads to shed attenuated polio virus reverting to full strength.

And that's definitely the reason they didn't get vaccinated, which probably wasn't fundamentally egocentric at all /s

Huh? They did get vaccinated.

EDIT: It is possible the import could have come from an unvaccinated person too, having gotten it from someone who has been vaccinated. But that the virus is vaccine-derived means the ultimate source is someone who got the vaccine.
