Antibody Titer Kinetics: Primary vs Booster Response

Vaccination doesn't just deliver an antigen — it trains a memory. This simulator models the two-compartment kinetics of a real humoral immune response: administering a primary dose triggers a slow plasma-cell secretion burst that raises antibody titer over one to two simulated weeks before decaying, while a booster dose recruits the memory B-cell pool left behind by the first exposure to fire a faster, higher anamnestic response. Watch the antibody particle swarm and memory-cell ring evolve in 3D, track titer against a protective threshold on the scrolling graph, and read live numeric titer, days-since-dose and memory-pool values as the underlying ODE integrates each frame.
