The vaccine hasn't stopped spread in rich countries, why would it do so in poor countries?

Also there haven't been enough variants as to determine that most variants are coming from poor countries. Speaking of delta, India has more population than the entirety of Europe. Mathematically it makes sense than a variant could come from there regardless of whether the vaccine does anything.

It has greatly slowed the spread. The highest vaccinated countries have almost stopped it. There is every reason to believe that high vaccination across the world would stop covid, and anything less will ensure continued spread (and mutations).

People demanding an all or nothing from a vaccine are missing the big picture.

The highest vaccinated countries have almost stopped it? Israel had among the highest vaccination rates in the world prior to its most recent peak, which has now declined. Other countries are going through the same thing. There is only a very rough/weak correlation between vaccination rate and positive cases.
