South Korea's struggle to boost coronavirus vaccine supplies is threatening to overshadow President Moon Jae-in's first summit with U.S. President Joe Biden, with pressure mounting on Moon to secure more and faster deliveries of U.S.-made shots.
Moon had hoped to use the Washington meeting next week as a chance to highlight South Korea's relatively successful response to the pandemic, a key legacy in his final year in office.
But uncertainties in the country's vaccine rollout amid global shortages and shipment delays are deepening public skepticism over Seoul's goal of reaching herd immunity by November.
