Explain vaccination memory
A vaccination diagram in a neurobiology tutorial shows antigen exposure followed by memory cell formation. Explain why a later infection can be controlled faster. Use the diagram labels, physiology pathway, feedback loop, or data values before answering. Enter the answer and choose the interpretation that best matches the biological evidence.
Worked practice: biological evidence and answer
Use the labelled biological evidence first, then connect it to the final answer.
