That'#s really interesting, thanks.Vaccine used until 2016 causes a new variant. Yay.
One strain of polio was eradicated in the wild in 1999. But a few cases have been popping up because of an old vaccine.www.vox.com
Can I presume that nobody from these countries gets into Ireland without a full and genuine vaccination card?
It makes intuitive sense that a live virus vaccine , orally administered, might result in some viral shedding which, in turn could casse problems in an area with poor sanitation. I'm always a little wary of "intuition" however, as it is subject to cognitive biases. Still, it;s a good start for further exploration.
As regards your second point, restricting immigration to people from those countries, there's an ECDC paper on this. The Executive summary describes what should be offered to newly- arriving immigrants.

The discussion on whether immigration should be limited to those with already complete vaccination records is a different discussion. From a scientific perspective, i would wonder whether the risk to the risk posed to the indigent population would justify such a restriction.
