Moderna vaccine shipments to South Korea have resumed starting with the arrival of more than one million doses on Thursday.

According to the state vaccine task force that day, a Korean Air flight carrying around one-point-02 million doses landed at Incheon International Airport at 3:29 p.m. 

It is part of six million doses the U.S. pharmaceutical company has agreed to supply by the end of this week. Senior Health Ministry official Son Young-rae said earlier that these secured supplies will begin to arrive on Thursday, and may even exceed the initial amount. The remaining doses are expected to arrive by Sunday. 

Moderna previously notified Seoul that it could only send less than half of the eight-point-five million doses of the August shipment due to production glitches.

South Korea promptly dispatched a government delegation to its headquarters in Massachusetts to file a complaint, after which the U.S. company promised to send seven-point-01 million doses by the end of this week. Over one million doses arrived on August 23.

Meanwhile, 526-thousand out of one-point-05 million doses of the Pfizer vaccine that South Korea purchased from Romania under a bilateral agreement also arrived Thursday afternoon.
