The World Wellness Group on Thursday once more expressed issue that aggressive booster campaigns in wealthier countries could further more exacerbate international disparities in accessibility to vaccines.

“If we seemed at the data nowadays, even in advance of Omicron, we are observing substantial-money nations administering far more booster doses than even vaccines that are becoming supplied in building international locations,” Richard Mihigo, the coordinator for the Planet Overall health Organization’s vaccine program in Africa, reported at a news conference.
