Health Canada approves drug to treat COVID-19 in immunocompromised patients, AstraZeneca says – CBC

The antibody-based therapy Evusheld previously used to prevent COVID-19 can also be used as a treatment

Some people in Canada who are particularly vulnerable to illness from COVID-19 have a new injectable treatment option.
