I think a big part of the herd immunity failure is that the variants that tend to be more vaccine resistant, are popping up in countries that had relatively low vaccination rates (too low for herd immunity). The fact those countries have allowed the virus to propagate more means more chances for variants to arise and spread to other regions.
I understand some of those regions have less than great health care systems, but as long as there are regions with large unvaccinated populations, and as long as we allow people to travel back and forth to those regions, we are going to keep seeing the virus evolve and vaccines are going to continue to struggle to keep up with variants.
