The World Health Organisation's (WHO) chief scientist, Soumya Swaminathan, has said the world is not yet at the end of the Covid-19 pandemic as there will be more coronavirus variants, reports Reuters.

“We have seen the virus evolve, mutate ... so we know there will be more variants, more variants of concern, so we are not at the end of the pandemic,” Swaminathan told reporters in South Africa, where she was visiting vaccine manufacturing facilities with WHO Director-General Tedros Adhanom Ghebreyesus.
