More Covid-19 Vaccines Are Reaching Poorer Nations, but Slowly

Vaccine makers have delivered more Covid-19 shots to the world’s poorest nations in recent months, but wealthy countries are still receiving a disproportionate share. The unequal distribution, global health experts say, has hampered efforts to move past the pandemic and allowed new variants like Omicron to emerge. High-income nations, which include the U.S. and are home to a sixth of the world’s population, have received nearly half of all 5.9 billion doses made by the four major Western vaccine makers, according to healthcare data company Airfinity.
