With coronavirus vaccine at least 12-18 months away and sharp rise in cases, Pakistan is beginning clinical trials of a potentially promising therapy to treat patients infected with Covid-19.

The treatment involves injecting antibody-rich plasma from recovered Covid-19 patients into those who are still infected. Antibodies, also known as immunoglobulins, are proteins in blood that fight specific bacteria and viruses. The donor antibodies temporarily help a sick person fight infection effectively.
