What is the definition of vaccine?
ANSWER
A vaccine trains your immune system to produce antibodies( proteins that fight disease), exactly like it would if you were exposed to the disease. But vaccines work without making us sick from the infection because vaccines typically contain pieces of dead, weakened, or lab-made substances that stimulate your immune system.
