As the United States and Europe ramped up their COVID-19 vaccination programs, the Asia-Pacific region, once lauded for its pandemic response, struggled to get them off the ground. Now, many of those laggards are speeding ahead, lifting hopes of a return to normality in nations resigned to repeated lockdowns and onerous restrictions.

The turnabout is as much a testament to the region’s success in securing supplies and working out the kinks in their programs as it is to vaccine hesitancy and political opposition in the United States.

South Korea, Japan and Malaysia have even pulled ahead of the U.S. in the number of vaccine doses administered per 100 people — a pace that seemed unthinkable in the spring. Several have surpassed the United States in fully vaccinating their populations or are on track to do so, limiting the perniciousness of the delta variant of the coronavirus.
