The Korean drug regulator is set to approve the use of a COVID-19 vaccine developed by U.S. drugmaker Novavax this month, making it the fifth vaccine to be used in the country.

The Korea Disease Control and Prevention Agency (KDCA) said Friday that the Ministry of Food and Drug Safety, which is currently reviewing Novavax´s Nuvaxovid, is expected to give the green light by the end of January.
