i think this useful to you...

Answer 2

THE REASON IS ANTIGEN-ANTI BODY
REACTION
THIS REACTION IS USED IN VACCINES

WHAT IS ANTI BODY-ANTI GEN REACTION
WHAT IS ANTI BODY
WHAT IS ANTI GEN
----------------------------------------------------------
1)ANTIGEN ;-ANY THING WHICH ENTERS OUR BODY LIKE DUST,MICRO ORGANISMS
WHEN AN ANTIGEN ENTERS OUR BODY, OUR BODY PRODUCES A DEFENCE PARTICLES
2)ANTIBODY:-THE ABOVE PARTICLE IS
CALLED ANTIBODY

THESE ANTI BODY STAY IN OUR BODY LIFE LONG

3)ANTIGEN-ANTIBODY REACTION :WHEN A ANTIGEN ENTERS OUR BODY, OUR BODY PRODUCES ANTI BODIES WHICH FIGHT AGAINST THE ANTI GENS
----------------------------------------------------------------

SO IF A ANTIGEN WHICH CAUSES CHICKEN POX, ENTERS INTO OUR BODY, THE ANTIBODIES ARE PRODUCED
UNTIL THEIR REACTION HAPPENS,WE EXPERIENCE CHICKEN POX,
AND IT IS CURED

AND AGAIN IF CHICKENPOX ANTIGEN ENTERS, THERE ARE ALREADY ANTIBODIES IN OUR(because antibodies stay life long)BODY,SO IT IS EASY TO FIGHT AGAINST THEM,
SO THERE WILL BE LESS CHANCES.OF GETTING CHICKHEN POX AGAIN AFTER EXPERIENCING IT ONE TIME
