(AP) — Fueled by vaccinations and government aid, the U.S. economy grew at a solid 6.5% annual rate last quarter in the clearest sign to date that the nation has achieved a sustained recovery from the pandemic recession. Thursday’s report from the Commerce Department estimated that the nation’s gross domestic product — its total output of goods and services — accelerated in the April-June quarter from an already robust 6.3% annual growth rate in the first quarter of the year. For all of 2021, the economy is expected to expand about 7%. That would be the strongest calendar-year growth since 1984. And it would mark a sharp reversal from last year’s 3.5% economic contraction — the worst in 74 years — as a result of the pandemic.
