” This is to guarantee that COVID-19 vaccines continue to offer WHO-recommended levels of security versus infection and illness by VOCs, consisting of Omicron and future versions.”
The group will think about a modification in vaccine structure to guarantee dosages continue to satisfy WHO requirements.
