As CTV reported, the monoclonal antibodies have been approved for emergency use in the US. They were also used to treat former President Donald Trump (74) when he had Covid-19.

The antibodies used to treat Winston came from a supply that was not approved for human use.

On January 11, several gorillas in Winston's eight-member troop tested positive for coronavirus.

Because Winston was lethargic, had a mild cough, was congested and happens to be an advanced in age, he was examined under anesthesia.
