Vaccines work by generating an immune response in the body against some kind of pathogen—a virus, bacterium, or some other agent that causes a disease. A vaccine exposes the immune system to a less-threatening version of the pathogen and, in effect, primes it to recognize and quickly eliminate a more dangerous version should it ever invade the body. Here, see how various kinds of vaccines are made.
