The comments by WHO Director-General Tedros Adhanom Ghebreyesus mark a change in tone just months after he said that the world has never been in a better position to end the pandemic."We are much closer to being able to say that the emergency phase of the pandemic is over, but we're not there yet," Tedros said on Friday.The global health agency estimates that about 90% of the world's population now has some level of immunity to SARS-COV-2 either due to prior infection or vaccination."While COVID-19 and flu can be mild infections for many, we must not forget that they can cause severe illness or even death for those most vulnerable in our communities", Mary Ramsay, director of public health programmes at the UK Health Security Agency, said.The WHO urged governments globally to focus on reaching those at risk, such as people over the age of 60 and those with underlying conditions, for vaccination."
