Stimulate an immune response
Explanation:
The vaccine is a preparation that contains a weakened or killed form of microorganism (or part of them) that stimulates the immune system to produce memory antibodies to recognize that microorganism in the future. After the body produces the memory antibodies, if a person is in contact with that microorganism the body recognized them as “strange” and the body response to killing them is faster before the infection. In some cases is necessary to apply various doses of the vaccine in a certain time to maintain the memory antibodies.
