A new vaccine was developed and then tested on
a large sample of individuals. This new vaccine
will be considered effective if it helps prepare
the body to fight future invasion by
(1) inhibiting the response of red blood cells
(2) stimulating the reproduction of microbes
(3) inhibiting the action of immune cells
(4) stimulating the production of antibodies

    so in future when you catch the same cold your body will be able to produce antibodies quickly because the memory cell remembers the antibodies that fights off the colds
