The object of vaccination is to stimulate a response against a harmless introduced material which will produce a future protective response against a similar, dangerous invader in a fashion that is safer, faster, stronger and more precise than can be expected by allowing natural exposure.

Prions are infectious proteins which cause the production of subacute spongiform encephalopathies. They are variants of normal cellular proteins, which have a predilection for depositing extracellularly in a β-pleated sheet configuration, and then causing changes in normal cellular homologs to deposit with them and build up an impermeable matrix. Considering the engineering design of the immune response, can you predict the FIRST point at which immunity will be absent from the lesions of such amyloidopathies?CorrectIncorrect
Which of the following is true of the innate immune response?CorrectIncorrect
