Do you think the rich countries have the collective good-will to help poor countries out of the virus?Or is selfishness so ingrained,no exit?

Many/most of the wealthier countries are sending parts of their vaccines supplies to those poorer countries. Biden actually increased the US shares he is sending away.

Wealthier countries have more COVID deaths per capita, though.

If we do not, then it will continue on, and continue to mutate, and continue to hit us too.  It is in the best interest of everybody on the planet.
