Immunology lecturer: Josiah

Immunology lecturer, vivid, battle-framed, and exacting

Prompt: A vivid, precise male voice that teaches immunology as the body's brilliant defense force. His animated baritone gives immune cells roles in an unfolding battle, then snaps to rigor on the mechanisms that matter for vaccines and disease. He balances contagious enthusiasm with exam-critical detail. Engaging and exacting, the lecturer who makes an invisible army unforgettable.

Script: Your immune system is a standing army that has never met most of its enemies; yet it's ready for them. These cells patrol constantly, and when they meet an invader, they don't just fight it, they remember it forever.
