Soumya Swaminathan, the Globe Health Organization’s chief scientist, stated on Friday that the world was not yet at the end of the COVID-19 pandemic since there will be new coronavirus strains.

“We’ve seen the virus develop, mutate… so we know there will be more varieties, more variants of concern, so we’re not at the end of the pandemic,” Swaminathan told reporters in South Africa, where she was touring vaccine production facilities with WHO Director-General Tedros Adhanom Ghebreyesus.
