The poorest countries may experience delays in receiving Corona vaccines through Kovacs due to technical problems at a Plant in South Korea and problems in securing export licenses from India, and some 90 million doses of The Oxford AstraZeneca vaccine may be affected by  these problems, especially after reports that India has temporarily suspended vaccine exports amid a rise in new infections there, UNICEF said.

“The Kovacs facility has informed participants about dedicated quantities of the Oxford-AstraZeneca vaccine produced in South Korea, which will be lower than planned in March, as some countries was expecting its arrive this week,” a UNICEF spokesman said.

“This delay is due to the challenges facing the global supply environment and the challenges the company faces in increasing supply quickly and improving production processes for these early deliveries,” he said, noting that “AstraZeneca has informed Kovacs that it will provide late quantities by May.”
