Yes. Synthetic antibodies are a thing, but they are very expensive and very hard to produce (from what I inderstand). Using animals when possible (for example horses, for the production of snake venom antidotes) seems more efficient in cost, volume and time. Take for instance this crisis. They just need the plasma of immune individuals to give temporary immunity to sick or at risk individuals. It doesn’t scale but it works.
