Director-general of the World Health Organization (WHO) Tedros Adhanom Ghebreyesus said during an update on Tuesday that he was “particularly concerned” about countries with low COVID-19 vaccination rates, “as people are many times more at risk of severe illness and death."
"I'm proud COVAX delivered its one billionth dose over the weekend. Of course, it's not enough and we should do more," he said. "At a time of Omicron, it remains more important than ever to get vaccines to the unvaccinated."
Developing nations have struggled with vaccination, after limited doses of expensive vaccines were snapped up by wealthier countries.
During the update, WHO chief scientist Soumya Swaminathan also said there is currently no evidence that healthy children and adolescents need booster doses of the COVID-19 vaccine. She added that while there seems to be some waning of vaccine immunity over time against the Omicron variant, more research needs to be done to ascertain who needs booster doses.
