I DONATED CONVALESCENT PLASMA FOR MOST OF A YEAR, SO I HOPE SO: Study: Blood plasma may be effective against COVID-19 when used correctly. “Blood plasma collected from people who have recovered from COVID-19 works well as a treatment for those who develop serious symptoms from the virus, a study published Monday by JAMA Internal Medicine found. To be most effective, however, the plasma, administered via transfusion, must be initiated early in the course of the disease, in hospitalized patients, before they require high levels of supplemental oxygen or become hypoxic, the researchers said.”

Yes, most Covid treatments work better if you administer them before people are actually dying.
