Evusheld can act as another layer of protection, alongside vaccines, for people who are at high risk of COVID-19 infection, according to AstraZeneca's statement.

The U.S. Food and Drug Administration on Wednesday authorised the use of Evusheld to prevent COVID-19 infections in individuals with weak immune systems or a history of severe side effects from coronavirus vaccines.
