"There is a real threat of virus mutations into more infectious and deadly variants that may be resistant to existing vaccines," the UN Secretary General quoted TASS as saying.
Guterres also called for "to significantly increase the production of vaccines worldwide, as well as ensure their universal availability."
“Vaccines are rapidly emerging in high-income countries, while the world's poorest countries are lacking them,” he said.
In addition, Guterres, speaking at a forum in Davos, announced the worst economic crisis in a century amid the COVID-19 coronavirus pandemic.
