    Study Notes

    Innate and Adaptive Immunity

    • Innate immunity is the body's first line of defence. It is non-specific and immediate/hours
    • Adaptive immunity is a later response to specific pathogens. It is antigen dependent and takes days/weeks.
    • Innate immunity has no memory, whereas adaptive immunity has memory.
