World Health Organization Director-General Tedros Adhanom Ghebreyesus on Friday said that the coronavirus pandemic is a once-in-a-century health crisis, the effects of which will be felt for decades to come.
“The global coronavirus outbreak is the sort of disaster whose effects will last far into the future,” he added.
The pandemic has killed more than 670,000 people, with more than 17 million cases diagnosed.
More than around 150 pharmaceutical companies are working on vaccines.
“Although their first use cannot be expected until early 2021,” the World Health Organization said last week.
