WHO chief Tedros Adhanom Ghebreyesus reported on the outcomes of the latest meeting of the Emergency Committee on COVID-19, held online the previous day.
Experts issued a statement calling for upgrading national capacity for genome sequencing, and greater data sharing, in efforts to monitor and respond to changes in the virus.
Tedros told journalists he was pleased they also emphasized that vaccines must be rolled out equitably.
“Health workers are exhausted, health systems are stretched and we’re seeing supplies of oxygen run dangerously low in some countries”, he said, speaking during the agency’s regular end of week press briefing, from its Geneva headquarters.
“Now is the time we must pull together as common humanity and rollout vaccines to health workers and those at highest risk.”
