IMF warns that vaccine "haves" and "have nots" is widening with rapid vaccine rollout critical

The International Monetary Fund is warning a rapid rollout of vaccines around the world is now critical to confront more deadly mutations of the COVID19 virus. 

While the global economic recovery remains on track and Australia's outlook has been slightly upgraded, the IMF is warning that poorer developing nations struggling to vaccinate are most vulnerable. 

ABC's Peter Ryan says the IMF says rising inflation if sustained could force central banks to raise interest rates sooner than expected.
