South Korea is considering plans to vaccinate workers at key businesses including chip and electronics firms to prevent disruptions to production, an official at the Korea Disease Control and Prevention Agency (KDCA) has said, according to Reuters.

The labour ministry has sent letters to companies including Samsung Electronics Co Ltd, SK Hynix Inc and LG Electronics Inc seeking information on their Covid-19 vaccination needs, the Maeil Business Newspaper reported, citing government and industry sources.

The KDCA and labour ministry have said they were discussing such options with government agencies but no specifics have been decided. Samsung Electronics, SK Hynix and LG Electronics said they had received the letter.

The move comes amid a global chip shortage that has affected manufacturers around the world, particularly carmakers. Samsung and SK Hynix are the world's top two memory chip makers.
