US: The U.S. health regulator has withdrawn emergency-use authorization for AstraZeneca's COVID-19 antibody cocktail Evusheld as the treatment is not expected to neutralize the currently dominant XBB.1.5 subvariant of Omicron.
The Food and Drug Administration (FDA) had limited Evusheld's use earlier this month for the same reason.
Omicron subvariant XBB.1.5 has been spreading rapidly in the country since December and it made up nearly half of all U.S. COVID-19 cases last week, according to government data.
Evusheld was first authorized in late 2021 by the FDA to prevent COVID-19 infections in individuals with weak immune systems or a history of severe side effects from coronavirus vaccines
