antigen
A harmful substance that triggers antibody production in the immune system
antibody
proteins in the blood that fight specific invaders like bacteria, viruses, and foreign substances.
how the body comes to produce antibodies against a specific invader
B cells produce antibodies, Antigens stimulate B cells to multiply, Plasma cells (replicated B cells) release many antibodies into the body’s fluids
difference between the primary and secondary antibody responses
B cells are challenged, B cells are not challenged
Vaccine
a biological preparation that provides active acquired immunity to a particular infectious or malignant disease.
How a vaccine works
Vaccination primes the immune system to recognize antigens as foreign—>antibody prod is triggered, memory of virus/bacterium is formed—> Upon re-encountering virus/bacterium, immune syst rapidly prod antibodies—-> immune cells activate —-> Swift response protects against the disease
