World Health Organisation (WHO) chief Tedros Adhanom Ghebreyesus said on Tuesday that the Covid-19 pandemic is far from over. "This pandemic is nowhere near over," a report quoted Tedros Adhanom Ghebreyesus as saying. Tedros Adhanom Ghebreyesus also raised concerns over low vaccination rates in some countries and cautioned against a narrative that the fast-spreading Omicron variant is risk-free. "Omicron continues to sweep the world. I remain concerned about countries with low vaccination rates, as unvaccinated people are many times more at risk of severe illness and death," Tedros Adhanom Ghebreyesus said in a tweet.
