UNDATED (AP— In its latest forecasts, the International Monetary Fund says the rollout of COVID-19 vaccines and vast sums of government aid will accelerate global economic growth to a record high this year in a powerful rebound from the pandemic recession. The 190-country lending agency says that it expects the world economy to expand 6% for 2021, up from the 5.5% it had forecast in January. It would be the fastest expansion for the global economy in IMF records dating to 1980.
