Innate immunity, found in all metazoans, provides immediate, non-specific defense through germline-encoded receptors, while adaptive immunity, unique to vertebrates, involves specific responses with memory. It highlights immune cells, pattern recognition receptors (PRRs), and the role of adjuvants in enhancing vaccine responses.
